In Q2 of 1862 a Martha Bartholomew m. in Newmarket, vol 3b p. 841, either James Dunthorpe or Charles Livermore.  More for the 1881 census to sort out?  But it didn’t, perhaps one had died by then.

Her birth in Mildenhall district, Suffolk is correct as that includes Kentford.

Her possible death:

Surname   First name(s)   Age   District   Vol  Page
Deaths Dec 1870   (>99%)
Livermore Martha 30 Newmarket 3b 376

But her last child, Margaret Ida, was born on 22 Dec so Martha must have been alive for that; sounds like a death in childbirth issue so she would have died pretty close to 25th Dec.
