Pochin was a director of TIC and was a Lord at the House of Commons. Thats all I know about him .Markham Colliery was named after Andrew Markham and Wyllie Colliery the same; All linked to Tredegar iron Company.
Henry Davies POCHIN was a Director of the TIC. He was a North Walian with extensive property at Bodnant Estate in Denbighshire. He was a ship owner, ship builder and farmer. He spread his money into industry and bought into the TIC. When that company wanted to expand its coal interests, it bought the land 3 miles south of Tredegar. The first sod was cut by his daughter, LAURA POCHIN in May 1876 and it is after her that the colliery was named. (Source : "The Tredegar Company - One of the South Wales Coalfield's Big Three" by Leslie M Shore).
Laura Pochin then married McLaren, Chairman of TIC but also chairman of John Brown Shipbuilders (which built all the "Queens!. Having married Laura, Bodnant became the McLaren home. A McLaren lives in the house now, he is a QC. The gardens belong to the National Trust (I do not know whether he was chairman of those companies at the time he was married). My father in law worked at McLaren but that is another story
