if that's the correct 1881 ref RG11/5244 folio 13 pg 23, I've checked the birth registration of son Morgan R aged 8 months on the GRO index and mother's maiden name shows as Edwards
Morgan Rees Price sept qtr 1880 Bedwellty vol 11a pg 101 - he died in 1882.
There's also a birth reg for Thomas M Price in 1875 mmn Edwards which leads to
Sarah Ann Price march qtr 1873 Bedwellty vol 11a pg 103
which makes her a bit younger than the 1901 census would suggest. What age is given on the marriage cert? And what address? Do the name of the witnesses help?
William & Mary and baby William are on the 1871 census
Mount Pleasant, Sirhowy RG10/5323 folio 64 pg 14
William Price head mar 26 collier b. Breconshire, Rassau
Mary wife 24 b. Beaufort
William son 1 b. Mount Pleasant
Possible marriage 13 April 1865 in Llanelli Breconshire for William Price aged 20, miner and Mary Edwards 19, both of Brynmawr, his father William, miner, and her father William, collier.
When did William & Sarah Ann die? Have you checked the 1939 register for them?
