This Gems listener just can’t find her grandmother’s parents. It may be time to apply two powerful approaches to solving this mystery.

Recently we shared 6 sources that may name an ancestor’s parents. Afterward, I got a follow-up email from Lynn, who is still stumped:

“I read these [suggestions] but none of these were of any help with finding records on my grandmother[‘s parents]. The Social Security record didn’t list her father; as far as I can find there are no birth records for her where she claims she was born. Her father’s name isn’t on her death record because mom didn’t know what her grandfather’s name was. And her mom & ‘grandmother’ disappear from the Detroit city directory about the time she would have been born. They only show up again two years later for her grandmother and five years later for her mother. I put her ‘grandmother’ in quotes because that may be a sham: my grandmother’s mom worked for the other lady as a live-in servant.”

Lynn sounds a little discouraged! When typical record sources don’t reveal what we want to know, it’s often time to try two more advanced approaches: cluster research and DNA.

Applying Cluster Research to “Missing Parents”

I’m guessing Lynn has already beaten the bushes for ANY other records on grandma’s mom, especially marriage and divorce records. But I’m wondering whether she’s looked for other records about the woman grandma’s mom worked for. I don’t know the exact timing, but there was a huge migration to Detroit in the early 1900s. These two ladies could have been from anywhere. Chances are good they were from the same place, though. She’s definitely a “person of interest” to research. Records about this employer/grandma may lead to clues about her grandma’s own origins. So a first step may be for Lynn to research where the employer/grandma was born, and see if grandma’s family name shows up in the same place.

That concept is called cluster research, where you try to recognize little migratory groups and use other members of the group to learn more about your own ancestor of primary interest. It’s a concept I talk with Gems Editor Sunny Morton about in the November 2015 Family Tree Magazine podcast, which I host.

DNA for “Missing Parents”

The other avenue that it may be time for Lynn to try is DNA testing. Depending on which test she takes, her results may lead to common relatives on either side of her grandmother’s mother’s family. For example, if grandma had a full-blooded brother (which may be impossible to know for sure), a DNA test on one of his male descendants may point to the identity of the unknown grandma’s dad.

I recommended to Lynn that she check out our series of DNA guides written by our resident DNA expert, Diahan Southard. They will walk you confidently through the next steps in your genetic genealogy journey.
