I think Jane (the mother) is at Ysanteg(?) Llanddarog in 1851, age 29, unmarried a Labourer’s daughter. With her is a brother Thomas Evans, age 21, unmarried a collier.
In 1861 I think sh is “resident” at Garnlwydfawr, age 38, unmarried a dressmaker, born Llanddarog. Garnlwydfawr is a farm owned by John Griffiths age 50 of Llangunnor.
I can’t obviously find her in 1871.
In 1881 she is with her sister age 58 a former Laundress.
I think this may the marriage of Thomas Evans in Llanddarog. 22 Jul 1859, Thomas Evans, age 30, Bachelor, Collier of Pantig(?) and Margaret Jones, age 28, Spinster of Rhyd-y-Dalan. Fathers were John Evans and Thomas Jones, both Farmers.
In 1861 Thomas and Margaret are at Tregursens(?), Llanddarog. Thomas 32 a Collier of Llanddarog and Margaret 30 of Llangendeirne with a Daughter Mary Evans age 1 of Llanddarog.
In 1871 same address, Llanddarog
John 43 Collier
Margaret 39
Jemima Jones 21 Step Dau Seamstress Llanddarog

I think this is the birth entry for Dau Catherine which gave me the mmn of Jones
EVANS, CATHERINE mmn JONES
