St Margaret's Church sits right next to Westminster Abbey. It is the historic church of the House of Commons and as such is something of the poor cousin to Westminster Abbey. My ancestor who was baptized at this church was Richard Hatton. His descendents were Haddocks-my Mother's side of my family.
Another Griffin family ancestor. John Pike was a member of this church. I find it interesting that it is a guild church, so we might expect John Pike to be a skilled craftsman. The line of descent goes, Pike, Dawson, Waterer, Walters, Wadsworth, Shealy, Griffin.
