Trying to trace McCargo
My great grandparents moved to Glasgow from Islandmagee around 1905/6. My great grandfather was Alexander McCargo, great grandmother Margaret (Maggie), née Montgomery. I've traced some of the Montgomery side, but the McCargo side is proving more difficult. On the marriage registration Alexander gives his father's name as James Stuart. For years we thought this suggested he was born out of wedlock but recent investigation suggests has father's name could have been James Stuart McCargo. Having said that, his naval discharge papers say his parents names were Robert John and Ellen Jane (presumably McCargo). To complicate matters further his death registration states his father as Alexander McCargo and mother as Mary, née Stuart. The only date of birth I have for him is 31st October 1871 (from naval papers), which fits with his age on the 1901 census. The 1901 census states he was born Islandmagee but I can't find birth records for him. I did find an Alexander Stuart's birth but the birth date doesn't match. 1901 census has a William Gibson, relative, living there at the time (grandfather, great uncle?). I think one of Margaret's sisters, Eliza, married a William Gibson, but that William would have been much younger. There is definitely a Gibson connection as one of their sons was also called William Gibson McCargo (died aged 9).
Can anyone shed any light?
