I have Pennsylvania ancestors, many in Berks County, who I am sure are descendants of "Palatine" migrants, but I've not been able to connect them to the immigrant ancestors. However, for the less-common names I can identify names on passenger lists who are likely to be their ancestors, and I figure that if we try to research the (1) known ancestors and their families, (2) the immigrant ancestors and their families in Pennsylvania, and (3) the possible origins in Europe (Germany, Switzerland, Alsace) of the immigrant ancestors, we might get lucky and find the missing connections.
