I am from Dowlais and I've just discovered that there is a residential area of Rockville named Dowlais Drive: how did this come about? Dowlais had the largest ironworks in the world, with many of the workers moving to Pittsburgh for higher wages, also Donetsk in the Ukraine was founde by the Dowlais engineer John Hughes who was invited by the Tsar to build a works there, it was originally called Yuzovka before it's subsequent re-baptism to Stalino, but Maryland ?
