I know the George above is not John George, but his middle name may have been John. He arrived here under the name of George and was married as George. Only his death has him as John George.
I wonder if he had other members of his family come out, also.
Are you going to get a transcript of Mary’s death?
I see no Margaret Carty and only one Mary, close to her stated birth date:
CARTY, MARY no mmn

Something wrong with the marriage year on birth cert: 23 MAR 184
