Dear Virginia,
Where did he settle in the U.S.?
Sinse he was your GF or GGF..
Do you know where he is buried? If not do you know where your GFF is buried? Was there obituary regarding your most recent GF in the U.S.?
If there is..does it give clues to possible religious affiliation? If so..might give clue. Did your most recent G have siblings perhaps? Any information to be deduced by siblings?
Have U.S. census records helped?
