I am researching Jacob Stadler born NOV 1821 in Bavaria. He died in Illinois. I have not been able to find birth town, siblings or parents. He does not have any direct male line descendants so Y - DNA testing can not help find other Stadler connections. I am hoping the non-graying hair trait may have been passed down from him rather than his wife and that another Stadler researcher may have this trait in their line and may be related.
