That is the right family
If I were to make a guess, I would think they would have married at St John the Baptist Church in Bridgwater
The problem I am having is that the father was living with cousins in all the previous census' and the mother was living with her mother and her new husband, so I figure the marriage may give me some more to go on.
If this is not the right church, I couldnt make a better guess and I would probably opt to order the certificate, but I dont want to incase the information I am after isnt on there
