My ancestor Sarah Ann Tomkins married William Ebbs in Redbourn, Herts in October 1840. Her father is named as William Tomkins. On the marriage cert, William is described as a leather dresser. Later censuses all give her place of birth as Bermondsey, Surrey.
After research over quite a long time, I think there's a decent chance that she is Sarah Tomkins, born 6 Oct 1822 and baptised at St John Horselydown, Bermondsey 23 Nov. 1822, f. William (a tanner), m. Ann., living in Fair Street. I suspect Susan Tomkins (later Biggs), bapt. St Mary Magdalene, Bermondsey, 12 Sept. 1819, when William and Ann were in Assembly Place, was her sister. As always, later dates on censuses don't align and this may be wrong.
However, I'm now stuck as there are several candidates for William and Ann and I don't have enough information to take things further, either to reinforce my identification of Sarah or to identify her parents William and Ann.
I've looked everywhere I can think of online (I'm in Edinburgh, not London) so I'm looking now for any hints, tips or chance encounters that anyone may have.
Thanks in advance.
