How to Use Sanborn Fire Insurance Maps for Family History
Sanborn fire insurance maps help genealogists map out their ancestors’ neighborhoods and everyday lives. Nearly 25,000 digitized Sanborn Fire Insurance Maps are now on the Library of Congress website–and more are coming. Here’s what they are and how to use them for family history.
What are Sanborn fire insurance maps?
Sanborn fire insurance maps are a gem of a resource for those researching their roots in the U.S. (and parts of Canada and Mexico). These were detailed maps of city neighborhoods published periodically by the Sanborn Map Company beginning in 1867. They became available for a large number of cities by the 1880s and for many, were updated periodically for many decades. Today, the entire Sanborn fire insurance map publication series covers over 12,000 cities and includes over 700,000 maps.
Sanborn maps are valuable for “anyone with a personal connection to a community, street, or building,” explains a recent article from the Library of Congress. “They show the size, shape, and construction materials of dwellings, commercial buildings, factories, and other structures. They indicate both the names and width of streets, and show property boundaries and how individual buildings were used. House and block numbers are identified. They also show the location of water mains, fire alarm boxes, and fire hydrants.”
Here’s a sample map clipping from Elroy, Wisconsin:
How to use Sanborn fire insurance maps for your family history
The information in Sanborn fire insurance maps served the needs of urban planners, developers, and insurers, and now it can serve your genealogy research, too. A series of Sanborn maps is almost like stop-action aerial photography of your ancestor’s home and surroundings, with clues that can lead you to new documents and insights about their lives. Here’s a summary of how to use them:
1. Learn where exactly your ancestor lived. Look for a street name and house number in documents relating to your ancestors, such as city directories, deeds, WWI or WWII draft registrations, or passport applications. U.S. censuses have columns for house numbers and street names beginning in 1880, but are more likely to be filled in starting in 1900.
2. Find maps for that city. (See below for top places to find them online.) Find volumes published before, during, and even after your ancestors lived there.
3. Locate the map sheet with your family’s neighborhood using the map index in the front pages of the map volume. (Look for a street index.) Go to the correct map sheet.
4. Find the address. Look closely at the individual lot that belonged to your family, if you can identify it from the house or lot number (deeds may have lot numbers on them). You’ll likely be able to see the property boundary lines with measurements, along with the dimensions and footprint of buildings on the lot. Some details, such as as the building use, construction or whether it had asbestos or fire escapes, may be explained in Sanborn’s colorful map keys, like the one shown here from the Library of Congress website.
5. Check out the neighborhood. What kinds of buildings or features surrounded your family’s home? What schools, churches, factories, and other local institutions may have served your ancestors, and how far away were they? If you know where a relative worked, do you see the workplace nearby?
6. Compare maps from year to year. During the time your family lived there, the neighborhood likely evolved. There may have been new housing, business, road layouts, street names and numbering, and property use. You may see over time that an outbuilding was built, then transformed from a stable to a garage.
7. Use these details to create a description of your family’s everyday surroundings. Did they live in a brownstone duplex, frame home, or tall apartment building? Did their five-story walk-up have fire escapes? How close was their home to their neighbors’ home? How large was the lot, and what kinds of outbuildings were there? What kinds of buildings or features surrounded the property? How far away were the amenities they needed for daily life?
8. Note additional records to check. Do you see a nearby church, school, funeral home, cemetery or another institution that may have created records about your family? Follow up by looking for their records. (Click here to read my favorite online search strategies for finding records.)
Where to find Sanborn fire insurance maps online
Now we come to some excellent news. The Library of Congress now has over 25,000 digitized Sanborn fire insurance map sheets online! The collection description says these sheets come “from over 3,000 city sets online in the following states: AK, AL, AZ, CA, CO, CT, DC, DE, GA, ID, IL, IN, KY, LA, MA, MD, ME, MI, MO, MS, NC, ND, NE, NH, NJ, NV, OH, OK, PA, SD, TX, VA, VT, WY and Canada, Mexico, Cuba sugar warehouses, and U.S. whiskey warehouses.”
That’s fantastic, and the Library of Congress says more are coming. Recently they announced that over the next three years, they will be adding new map sheets every month until all 50 states are covered from the 1880s through the 1960s! By the end of the project, half a million Sanborn fire insurance map sheets will be online. So it will be worth checking back periodically to see if the maps you want are there.
Other digitized collections of Sanborn maps are online, too, and published collections exist at major libraries. Use the search strategies mentioned in this article to find them.

What To Do When Technological Changes Get You Down
Feeling frustrated by changing technology? Here’s a look back at a post I originally wrote in 2013 that addresses the mayhem tech changes can cause, and how a visit to a fast food restaurant changed my perspective on a particularly rough day.
The “Mayhem” commercials from Allstate are a riot, but of course all that mayhem isn’t all that funny when it’s happening to you.
Allstate Raccoon Mayhem Commercial
Sometimes it feels like technology companies are having a little mayhem fun with us when they get us up and running with their software program, or app, or phone, or tablet, or whatever, and then *BAM* they change it all up. Mayhem!
It’s not really that we don’t want new technology, it’s just that:
1. We sometimes get very little if any warning that it’s coming
2. The change requires investing time in learning all new ways to do something.
3. The change seems to be suspiciously benefiting the changer and not us – the “changee.”
4. We have to shift out of auto pilot into manual drive
…which means it takes longer to do tasks, and we tend to make mistakes more often because our brain, our eyes, and our fingers are all trained to quickly complete the task the old way.
I’m usually pretty excited about new technology and I love seeing what it can do for our genealogy efforts, but don’t think that I don’t have my moments when I just want to run screaming into the street and chuck my laptop in the gutter. We all have our moments. And I’m here to tell you that I feel your pain and have suffered myself, some mayhem this week, in fact, I call it:
Mobile Mayhem
See, the thing is, folks love their smart phones. Walt Mossberg, principal technology columnist for The Wall Street Journal just tweeted that according to an Experian marketing survey the average America spends an hour a day with his or her smartphone. And iPhone users spend more time than Android users.
Google, and specifically YouTube which they own, has definitely taken notice of all this smart phone savvy-ness, and they’ve decided to turn my world, and all the other YouTube Channel publisher’s worlds out there upside down.
I launched my YouTube channel way back in the stone-age, 2007, before Google even owned YouTube. And I have over 60 videos on the channel, and we’ve been diligently working on getting prepared for a while new phase of video production here at Genealogy Gems. So I have had my hands quite full on the video front.
YouTube has implemented a total redesign of YouTube channel pages. The goal is to make the channels mobile friendly, while still accommodating the wide range of full size computer screens that are out there. But in order to accomplish this, we as channel publishers have to scramble and get new artwork for our banner, produce a new introduction video and rearrange the video layout.
So how did I respond to this change you ask?
I ignored it, of course, until I had about a week left before they were set to flip the switch. And then this week all of a sudden it was an emergency to get my channel ready.
So I finally broke down and hired someone to create the new artwork, then I spent hours one morning trying to get all the changes made. My frustration level was growing a little because I just wasn’t happy with how the design of the new artwork was fitting the new layout. And there were so many other things I wanted and needed to be doing that week.
Then my sweet neighbor came to the door and my dogs, who think every knock on the door is a masked marauder, went totally ballistic, blasting through the room knocking over my morning coffee on their way to the door. So now I had coffee all over the carpet.
After my neighbor left I got the portable steam cleaner out to clean up the coffee stained carpet and it worked for a total of 45 seconds, then dribbled to nothing. So I went to the kitchen and set it on the counter to look at it and when I took the nozzle off it dribbled dirty water all over my freshly cleaned kitchen floor.
I spent the next two hours cleaning the kitchen floor, fixing the steam cleaner nozzle, and cleaning my carpet. And my YouTube channel was still not quite right, and I wasn’t sure how to fix it. Panic started to set in. All of a sudden I feared I would never figure it out, or get it done, and on top of that I was getting further behind on everything else I needed to do.
When my husband got home we went out for fast food because I hadn’t had a chance to do a thing about preparing dinner. So he listened to my day as we go through the line, and then I went to get my soda and I set my tray on the counter by the soda machine. Unfortunately I didn’t notice that the counter top was about six inches shorter than the tray, and my tray of shanghai beef and cream cheese won tons unceremoniously hit the floor.
At this point I was feeling pretty sorry for myself and pretty sure it was all YouTube’s fault.
Then, a woman my age came into the restaurant with her daughter and husband. She sat and waited while they ordered the food because she was in a wheel chair. And needless to say my perspective made a big course correction.
Maybe I don’t really know what frustration can be. And…get ready for it…maybe I over-reacted all day long.
She smiled at me and I smiled back and then I got to thinking back on my day. And I realized it’s so often not the change itself that causes the mayhem, but it’s our knee jerk response of fear to it.
If you have ever found yourself gritting your teeth as the next big technological roll out happens, or sometimes worse yet, the closing of a favorite tool like iGoogle or the Google News Timeline, here are some things to keep in mind:
First: Stay Calm and Carry On
Just like the famous saying from World War II Britain, we are much more effective in difficult times when we take a breath and stay calm, and then we continue moving forward to the best of our ability at our pace.
Often times it’s our lack of calm that causes us not carry on as usual, and in the end, brings more trouble down on our own heads.
The older I get the more I can see how human beings bring a lot of stuff on themselves. I didn’t start picking away at the new artwork and design until the last week before the change implementation because I was focusing on how they shouldn’t be changing it. And yea, that kind of thinking wasn’t hurting anyone but myself, because YouTube wasn’t about to call a halt to it because some channels didn’t like the idea.
And simple things, like I knew better than to set my coffee where I did, but I was so freaked out about the YouTube design I carelessly set it at dog level. And it was just silly to pull the nozzle off the steam cleaner over a clean floor rather than over the sink.
Second: The Technology Folks Probably Have a Good Reason for the Change
Sometimes it’s a financially driven change; they just can’t make it sustainable as is. And I would much rather see an inconvenient change than a complete disappearance of a Google or an Ancestry.
And sometimes it’s because the technology folks do have their eye on the future, and they see the big picture of how you and other users use your technology today. In the end the change will meet a pressing need, and they are striving to stay ahead of the game so we aren’t moaning down the road. YouTube’s change is a great example of that. They’ve made the case that a large percentage of users watch video from mobile devices and they challenged us as channel publishers to check our own analytics. And you know what, they’re right! I wasn’t keeping an eye on that but YouTube was.
Third: A Little Investment in Education can Go a Long Way
It’s OK if you have to slow down for a little while and spend some time getting re-educated. I decided to sign up for an online class YouTube offered channel publishers and in the first hour or so I came to better understand how my channel was going to benefit. And understanding the benefits will give you the motivation to take on the change.
I know, it’s hard to imagine that you can find even more time on education. But as I’ve said before on my Genealogy Gems Podcast, I think as genealogists we need to actually be budgeting a certain amount of time for education. Don’t leave it to be squeezed in in a panic. Allocate 10% of your research time for reading and education, and another 10% on staying organized, and I guarantee you remaining 80% will be much more productive!
The truth is, if my YouTube channel doesn’t look perfect yet, I trust that you guys will still be watching, and it certainly won’t stop me from publishing new videos.
And it’s sort of funny that this has been on my mind so much this week and I’ve been personally facing the YouTube change here at Genealogy Gems, because I just had the opportunity to sit in on a conference call with Ancestry.com where they provided a behind the scenes look at some of the changes they are working on for the upcoming months. Listen to Genealogy Gems Podcast episode 156 to hear the details.
After all I struggled with and all I learned from it last week, I found myself being much more open to the Ancestry changes. I was more focused on spotting the benefits to the genealogist, and I found myself admiring their commitment to continuous improvement. See the thing is, whether you are an individual genealogist or a big company like Ancestry, if you aren’t striving for continuous improvement you will fall behind, and the work will become more difficult because you are working harder than you have to.
Is an Archive Really What You Think It Is?
A lot of the best information about our ancestors’ lives is buried in an archive–NOT indexed online! Melissa Barker explains what an archive is and how to find one that might reveal secrets from your family history.
International Archives Day is Friday, June 9! Genealogy Gems contributing archivist Melissa Barker tells us what an archive IS and how to find one.
Recently, I was asked “What is an archive?” I was a bit surprised by this question since it came from a genealogist. I thought all genealogists knew about archives!
What exactly is an archive?
An archive is defined by the Society of American Archivists as: An organization that collects the records of individuals, families, or other organizations. The “organization” they are talking about could be any organization. It doesn’t have to be only a county archive, such as the Houston County, Tennessee Archive, or a state archives, like the California State Library and Archives. Archives include:
- A historical society that collects and preserves local records is also considered an archive.
- A genealogical society that accepts donations of family records is an archive.
- A museum that has exhibits and displays may also have records collections and would be considered an archive.
- Local public libraries that have genealogy rooms with records in them are archives.
The term “archive” is not solely used to represent a county or state archive. Any organization that accepts, collects and preserves historical and genealogical documents, records, memorabilia and artifacts is considered an archive, even if they don’t have the word “archive” in their title.
There are many different kinds of archives that can be accessed by genealogists. I always say, “There is an archive for everything.” Just because the building doesn’t have the word “archive” on it, don’t discount the fact that there is a “place” where there are historical and genealogical records being preserved or at the very least stored.
Tips for finding and visiting archives
The next time you are doing research on your ancestor in the area where they lived…
Ask around: There is always someone in the local area that knows the local history and knows many of the local families and most importantly; these people usually know where to find the records! This person may even be able to tell you about the family you are researching.
Ask around in the community, call the local library or the local Chamber of Commerce and ask, “Who is the local historian, who is the one knows about the families and history of the area?” I guarantee that you will be given a name. Ask where the records are stored or archived. Contact the local historical and/or genealogical society.
Be prepared to get dusty: There have been many times when I had arrived at the place where I was told the records were located. I was then shown a closet, the attic or basement and I was left to my own research devices to go through boxes and shelves of records. You have to ask the questions and you may even have to do some sleuthing in the local areas your researching in to locate the records.
Don’t leave any stone unturned. The records you are looking for could be sitting in boxes, archived or not, just waiting for you to find them. Remember: It’s not all online, contact or visit and archive today!
