Hi Roy,
I’ve just seen your post (albeit from two years ago!). John Mayo (bn 1809) was also my GG Grandfather. He moved to Blockley in Worcestershire (now Gloucestershire) where he worked as Coachman to George Rushout, the 3rd Baron Northwick at Northwick House. He married Sarah Drury on 21/07/1836 in Mickleton. Sarah was born at Weston Subedge in 1816. The Drury family tree (including Sarah’s marriage to John Mayo) can be viewed on the Weston Subedge page of the following website:
http://www.allthecotswolds.com/John and Sarah had at least 10 children. Their daughter Katherine Frederica Mayo, bn 30/12/1856, was my Great Grandmother (my father’s mother’s mother).
I don’t yet have details of John Mayo’s parents but would be happy to share what else I know if there’s some way we can get in touch.
Best wishes
Paul Winslow
