Bridal surname please

[LorraineJ]

This is for the wife of William Charles Thomson who was born 1839 in St Pancras. I gather that she was known as Mary Anne on the censuses and death certificate, but I don't known her maiden name. I believe she was born in Boston, Lincolnshire, was born about 1839 and died in Nottingham aged 83 in 1922.

I guess the only other right way would be to order the birth certificate of their son William born about 1876 in Newark.
