Hello Dewi, Rhymney Ironworks was not named that to start off with, it was called Rhymney Furnace and was started by 4 Bristol Merchants who were the owners and later Richard Crawshay of Cyfarthfa took an interest reason being was so that he could use this as a dowry for his daughter. Bute Iron Works upper Rhymney Valley was the opposite side of the bank to Rhymney Furnace and both became known as Rhymney Ironworks. A little village called Bute Town consists of three rows of terraced cottages and is a beautiful location and two of the houses are now a Museum and well worth a visit, but these cottages were some distance from the works but the Iron Works was situated in that location. And regarding Dre Evans I myself have not heard of this but back then there was not always named roads some were just classed as where they were close to, and Bute Town is on the edge of the village of Rhymney itself and not to be confused with the Valley named Rhymney. Regards Barbara
