I am sorry, but I don't find a connection in the information provided.

If you know the sister's name who immigrated to U.S. that might make a difference for me helping make a connection for you.

Have you worked on the Germany side of the research? If so, take a look for a familiar name or date in my German records. The German connections were made in the 1700's by the family priest and posted in the back of the official Catholic record book. . . great place to start if you can make a connection:-).
