Thanks again, Morgan,
I have the marriage certificate with Evan's place of residence as Glancennan (although difficult to read as that). The 1851 ties up with my previous research and I was going to search for it again but you've saved me the trouble! Thomas was Mary's father so it looks as though Evan and Mary met an untimely end, although matching up deaths of an Evan Evans and Mary Evans in Carmarthenshire, even narrowing it to Llandilofawr, is a major undertaking. I would need to get into the record office- not possible from East Anglia!
William Jones could be a useful lead, as the Jones and Evans families were united 13 years later when said William Evans, b.1840, married Hannah Jones (father William) rather hurriedly in the Llandilo RO on 7th June 1864, with their first child born in the next quarter. Most of the boys had Rees as a second name, with their father himself adopting it too, although not registered with a middle name at birth.
Going back to the 1851, my grandmother's place of birth was Wenault Isaf, Llandilofawr although the family home for many years was Tynewydd, Llandilofawr. These families were obviously closely linked, with land being apportioned to many and various over the years.
Anyway, now there are a few more glimmers of light through the brick wall and with help like yours, who knows what I may discover next?!
Very best wishes,
HH
