I have just spent months researching my direct ancestry which included immigration, manifests, naturalization documents, etc for people whose stories I mostly knew.
My question is, what are the best strategies for researching all the cousins and relatives who also came over but where I don't know names for sure or who their children are.
Some of them have come up as DNA matches however they often have as little information as I have
These are all people who came to/lived in the US so records should be out there.
It is getting started where I am stumped
For example, my GGF had a sister who I have as "unknown" Lefkowitz. Didn't come over at same time.
And I have a few children - Rose "UNKNOWN"
Knowing little, its hard to start a search.
