Marilyn,
All of these names coincide with my tree.I am decended from James Radcliffe Burton the son of William Radclffe Burton and Elizabeth Dent and therefore Emma's brother. David Conyers Burton was the Rector of the parish of Broughton by Brigg and was the son of Richard Burton (born 1732 Yarm, N. Yorkshire) and Mary (unkown). Richards parents were David Burton born circa 1700 and Mary Conyers born 1701 in Yarm. I have lots of information on the Burton family, too much to list here but I am happy to share.
