The village of Dowlais ( Black Brook) developed around the Dowlais ironworks under the management of Josiah John Guest it developed to become the largest ironworks in the world with the workforce of 5000 in the 1840`s. This iron company imported iron ore from Spain
One of the following generations
After R.T. Crawshay's death, his sons reopened the works,but soon closed again for a long and costly rebuild that was not complete until 1884, while a steel works was constructed. Crawshay Brothers, Cyfarthfa, Limited continued the business until 1902, when the works were sold to Guest Keen and Nettlefolds Limited, the proprietors of the Dowlais Ironworks.
By 1910, the steelworks had been forced to close again, and while it was briefly reopened in 1915 to aid in the production of materials for World War I, the works closed for the last time in 1919. It fell into disrepair until it was dismantled in 1928. The failure of the works was a devastating blow to the local community, as it had depended heavily on the works for its economic livelihood.
Guest Keen and Nettlefolds was transfered to Cardiff it later was known as Allied Steel and Wire I was employed as an industrial nurse there before its closure
