I'm looking forward to a response by the OP.
Although your theory, Annie, may not end up being right, you have worked hard through the wee hours to come up with it. Some additional information, answers to our earlier questions, and his or her thoughts on your bigamy theory from the OP might be nice.
I am especially interested in the children's birth entries or certificates, and would like to know exactly what John's name was on each of them, and also exactly what his occupation is written as.
Over to you "12toots".
