My grandmother, Mildred Blow, was originally Mildred McGraw and came from New Brunswick, Maine. She had one sister, Odella. It's interesting how the names were the same and both came from Nashua, New Hampshire, but Mildred's maiden name wasn't Blow. I'm still looking, though, for some additional information around upper New York in the late 1800's. All the evidence indicates the family may have migrated from Ireland to Canada to New York/Vermont, etc. So, thanks for the note.
