Thanks Sue.
The marriage of Henry and (Frances) Margaret Maxwell is right. I have previously posted some information on this board re: Patrick "Paddy" Maxwell, her father.
The other marriage is a possibility for our family given that the marriage is in the right date area, that he is a COACH driver and also that his father is James - a Joiner - which links back to his coach BUILDER and JOINER trade in earlier documents. I'll also request this marriage certificate in case that has more information.
