Finding paternal grandfather?

0

My paternal grandfather's name was not permitted to be on the birth register of my father. How does one find Unknown Unknown? through time and place? Thru DNA tests? through a GEDmatch? I think I've tried them all.


My autosomal DNA TEST shows a definite Jewish (Ashkenazi) dna from Lithuania now called Belarus. This person was very likely in Karlsruhe or Frankfurt in March 1907. My grandmother Anna's family seems not to have been rich enough to travel long distances as a general rule. An inference I made after meeting the three Bermans two years ago is that my and my son's keen interests in the arts comes from that Jewish family line. Other than that I don't know anything about him.

I am female and my father had no living male relatives except for his father. I had two sons and both had the same test taken.

As for a GEDmatch, I'm at a point where I've run it and received results. Now I must write people short letters to get further information.

2It really depends on the details. Where, when, do you know anything at all about your grandfather? If you are male, then Y-DNA testing may be most helpful. What exactly have you tried? – Harry Vervet – 2017-07-11T20:15:21.523

1What means - not permitted? It was hide for some reason? If we talk not about orphanage, maybe some records are still accessible? Could you please describe your situation more precisely? – GEORG GAAL – 2017-07-12T06:56:48.737

The archivist said that someone (could be his family, her family, my grandmother or her mate) did not want his name listed in the data on the birth register. Gm Anna left her child with her gm who was about 70 then so she could get to the US tp build a new life. Then her Gm brought him to the US after she found someone to marry. That man gave both of them a new last name and American citizenship. However, it's not clear where the man's place of Birth was. – R B Berg-Burnett – 2017-07-12T20:18:30.133

Even though you have been a user of this site for over a year I would like to encourage you to take the [Tour] to learn about its focussed Q&A format which is quite different from bulletin boards, discussion forums and other Q&A sites you may be used to. – PolyGeo – 2017-07-12T22:12:01.427

When you say "This person was very likely in Karlsruhe or Frankfurt in March 1907" are you meaning that your paternal grandfather was very likely in Karlsruhe or Frankfurt in March 1907. If so, I think it would be useful for you to [edit] your question to be more explicit about that and also to include the evidence that leads to you making that assertion. – PolyGeo – 2017-07-12T22:18:00.953

Generally, yes, when you are stuck with "paper" investigation, the only chance to get additional data is to pass DNA test and find matched persons. The only thing worth to be mentioned that DNA tests are very new technology and are not mature. The main problem is the size of database. I think that FTDNA's (the company #1 in DNA testing) database is not greater than 1000000 persons. Ancestry and 23andMe must be almost the same size. The chances that your relatives passed DNA test is small. But the time goes and the database grows. So someday your relative will get into database and you will see it. Also the algorithms of matching are not 100% reliable. They give as false-positive results, as false-negative too.

Yes, I have taken an autosomal DNA test at ftdna. I found some of his relatives, but there's a gap between them and my father. The two older ones have died now. The man had a resemblance to my father. – R B Berg-Burnett – 2017-07-12T20:11:31.340
