I have a Margaret Quarterman Matthews, allegedly born about 1809,who married William H. Stiles at Malling, Kent, in 1865, I can't find her marriage, so all I'm going on is the 41, 51, and 61 census, all of which say that she was born in Hertfordshire and one of which stated that it was in this mysterious place called Peters Chaffron, the spelling of which, incidentally, has been corrected by someone as though he knows that it exists. It doesn't look like Chalfont St. Peter, Ray, - Peters is definitely the first word. Getting the cert is not going to help as she appears to have married him in his parish, rather than the one she was born in.
