Thomas Price Jones and his wife Mary Williams lived in an area of south Wales called the Cynon Valley which lies in the county borough of Rhonnda Cynon Taf. They probably lived in the towns of Aberdale and/or Aberaman. Their church was in Aberdare.Thomas was a coal miner and probably worked at the Aberaman Ironworks, as at least one of his children was born there. The map and quoted text below are from the Rhonnda Cynon Taf website.
"Aberaman Ironworks were the last of the four ironworks in the Cynon Valley to be built. Founded by Crawshay Bailey in 1845 the first iron was puddled at Aberaman Colliery in May 1847. In 1848 the works had one working blast furnace, three engines, a forge, rolling and boring mills, brickworks and limekilns.
The works did not, however, prove successful in the long term. By 1854 they were out of blast although they were started again in 1855. A first attempt had been made to sell the works in 1862 for £250,000, but this appears to have been unsuccesful as the works were again put up for sale in 1864 following the retirement of Crawshay Bailey. The works were bought by the Aberaman Iron Company, although this company was wound up in 1867 when the whole concern was bought by the Powell Duffryn Company. The works had stopped in 1866 and were never again put into blast."
