Hello, in researching a paper on genealogy fro my son, I can across this post. From what I can tell Andrew H Diem migrated from Baden, Germany. He was born on May 6, 1830 and died in Buffalo, NY in 1908, My grandfather was Frank Diem, Buffalo, NY and served in WW I. Not sure how old he was when he died. He had two sons, Frank jr and William, the later of which was my father. Both som's served in WW II. contact me if you were able find out anythign else.
