William GARDNER b. c.1832 Stepney (or SE London) m. Ann Belsham
Samuel Tims GARDNER (nothing known except that he was listed as a cutler on Williams marriage certificate. Is
it possible that this actually meant a hawker of knives etc., or maybe a knife grinder etc.? Gardner is listed in
places as being a gypsy surname, which could mean that he was an itinerant hawker)
