In Watching "Finding your Roots" on PBS this morning, one person of the three who are featured had a missing person in her tree. The DNA geneticist, CiCi Moore (spelling!) decided that DNA was the only positive tool to use. She did find information leading to the woman's forebears.
Here's what NEEDS DOING: My father (b. Rudolf Berg) didn't know who his father was. His mother knew, but kept her silence. I think he was embarrassed about it (this came up in the 1950's when I was in high school in California). I truly want to find out who my father's father was. He was probably accurately described as "a German Jew," living at the time in Karlsruhe or Frankfurt am Main, DE.
His mother Anna Berg was genetically German. Her mother and brother had died early. Anna immigrated to the US alone via some money from a Schmid relative in Germany or possibly the Schmid woman who had immigrated before her to the US. (These Schmids are not known to me, but separately Anna and later her GM Rosa had visited one of them when she arrived in New Haven, CT, to start anew. Anna married a Robert Hilse in America, after 4 years of her new country.)
I can give more details if you are interested in working on this (and perhaps I'll add something later here that could be helpful.)
I do need your help. I'm not wealthy, but would be able to pay someone something.
