Hi, George William Langille & Elizabeth Thurlow married 1868 -- marriage record shows his place of birth was Tatamagouche and parents as Robert & _______. George W & Elizabeth had one child Lewis born about 1869.
Elizabeth Thurlow Langille must have died as I think George remarried a Rose Ann Williams in Halifax -- his place of birth on this record is River John -- parents are listed as Robert and Esther Langille -- father's occupation: ship's carpenter. If this is the correct George W -- he and "Rosa" had a few children: Leslie, Harriet, Gertrude, Bessie, Maude and Frank. Marriage record is shown on vital statistics under Rosanna Williams & George William Longille -- 1874.
There is a record in the1855 Massachusetts state census for a Robert Langill, wife Ellen (Eleanor), son George, 12, son Lewis, 9. This is a second marriage for Robert Langill born about 1816 in Nova Scotia who married Eleanor Campbell in the US -- she is not the mother of the children.
Not sure if any of this is correct, but may help in finding some info.
