Thank you Valda

for answering so many Cutler and Knight questions.
My mother's grandmother was Ada Louisa Cutler daughter of James Henry and Sarah Cutler's son Frederick Henry Cutler and his wife Clara Louisa Dean.
We've been finding the Cutlers marriages and the families in the census are often indexed as Cutter because of the cross on the T extending to the L.
It appears that James and Sarah Cutler had James Henry Cutler baptised late (20th May 1842) when he was about 19 or 20. Their eldest children being baptised at St Matthews Bethnal Green and then the youngest three baptised together at St Mary Magdalene Bermondsey in 1837. But then five days later (25th May 1842) they were back at the church having realised that they had forgotten Caroline Eliza (who was approx 20 in the 1841 census). I had thought it was a mistake on the IGI but now its possible to see the registers on line at Ancestry I have checked - and they did go back.
There is the marriage of a James Cutler to a Sarah Stevens on Ancestry on the 13th September 1807 at St Mary's Islington. This is the same date as James Henry Cutler and Mary Knight married 39 years later. The IGI has a Sarah Steven's baptised at Bethnal Green in Oct 1788 which is where Sarah said she was born in the 1851 Census.
