Ancestor John Hughes died May 1872 smallpox, 9 days duration. Notice of Interment by Burial Board lists occupation as "Collier Heolfach." Death registration in Ystradyfodwg, Pontypridd states he died Green Hill, small pox, occupation coal miner. Informant Wm Morgan in attendance at death resided Green Hill.
1871 Census (1 yr prior) lists John Hughes address as Ynysgau Road, Hamlet Clydach, occupation coal miner. No Wm Morgan living with family.
I'd like to determine possible colliery he worked in, as well as address where he died. Was Green Hill a location for small pox victims to be cared for or quarantined?
