Hi Jan, yes my research has revealed that his mother's surname was Field too, so even if William wasn't his father his surname would still have been Field if Anne was unmarried at the time. I've found their wedding (Anne Field m. William Field 23/7/1844 Westminster Middlesex), and Anne Field's parents are Joseph Field (and in his marriage record his wife is Priscilla Crumpton (m. 7.9.1809 Westminster Middlesex). This accords with the 1861 Census record of Priscilla Field (mother) living with Anne Field, Walter, Ellen and Frederick. I've found Priscilla living elsewhere in Marylebone in 1851 but can't find her anywhere in 1841. I was hoping she was living in Hampshire and that Annie was with her but no luck. Perhaps she was sent to the country to have the baby, or had a job there, but can't find her. Incidentally the birth certificate for Helen I got said William's job was Ostler and the death certificate for William in 1849 in Norwood describes him as a Fly Master who died at an Inn in Norwood. Is that an overseer of the fly coaches, or is this possibly the wrong William. Anne's death certificate describes her as widow of William "Inn Keeper", but that sort of embellishment seems common as time goes on!
