Interesting!I don't know anything about what happened to Martha Chisnall after the death of her parents in the 1870s, nor whether she had any children with her second husband, the unknown Mr Finch. She was a milliner, born about 1835, remarried between 1871 and 1875 so it's not impossible. In 1875 she was living at 11 Handford Road, Ipswich.
I've been looking backwards with this line, rather than tracing downwards.I'll certainly see what I can find out.I'm interested to know how far back your Finch and Chisnall searches go.
I'm a teacher with a brief holiday ahead.Time, record office opening hours and imminent arrival of the first grandchild permitting, I might try to find 'my' Mrs Finch in 1881.
