Hi Vicky and all
I have a Susan Anscombe born around 3 Jan 1817 in Cuckfield. She married a Jesse Dancy from Cuckfield Sussex, in 1837 after they had both emigrated to America. There is an IGI baptism for a Susan Anscombe on 29 Sep 1822 in Cuckfield with parents John and Sarah, But there is a marriage in Cuckfield in 1841 for a Susan Anscombe, so I imagine the Susan baptised in Cuckfield married there in 1841.
I also just searched and found no baptisms of a Susan Anscombe/Anscomb in transcipts of Bolney parish registers.
