My mother gave me my family tree which lead back 200 years. The oldets family name is Jauch:
Christan JauchAnna Jauch (Flaig) born 03.06.1791born 1794 Tuttlingen/Baden-WürttembergSt. Georgen area Villingen/Baden
These are the paernts of Katharina Lehr who is the wife of Friedrich Lehr (his parents were also called Lehr, he came from Posen/Poland).
The following ancestors went to Besserarabia (german: Besserarabien/ don't know the english term). Some families went like the Lehrs to Besserarabia which is located near the Black Sea. The family Anhorn is also one of my ancestors. They all came from Germany and went because of politcal reasons to the Black Sea. After years of living there, the ancestors left Besserarabia and went back to Germany. One family went to Hungary and then to Canada and today there are still Lehrs in Canada.I belong to the ancestors of a familily which went back to Germany.
I hope i could help you and when there following questions, you just have to write it.
