Diane has hit a brick wall. Joseph Norris married Mary Wheeler and had a number of children baptised in Berkhamsted St Peter. The problem is that there were two baptisms for Joseph, and a detailed analysis is unable to reliably identify which Joseph married Mary. My answer NORRIS, Berkhamsted & Northchurch, 18th century contains information which could be relevant to anyone with a similar problem in the 18th century - when there is no census returns to help, but where militia lists can be useful. The case is a classic Right Name, Wrong Body" , and all I can suggest is what I do when I hit a serious brick wall in my own research.
