One revealing fact was a marriage of his sister Margaret to a William John FRIEND. I am already investigating family links involve FRIEND, CHURCH, KEMP and FAGG. First thoughts suggest illegitimacies and other inter-family connections. Use of FRIEND as a middle name for KEMP family, similar use of CHURCH as a middle name, suggest possible maiden names and/or fathers of illegitimacies.
I’m getting into a right tangle!
