It is indeed, Rebecca married John Cooper, and they stayed in Merton as all their children were born there so it is a strong possibility that John was born there too. This is where I am stuck, I cannot find out who John was, when and where he was born. There is a record of a John Cooper marrying Rebecca in St George's Hanover Square, but why would she go to London to marry, there never has been any record of money in the family and St George's Hanover Square Westminster was I think a little too 'posh'.
