List,I just found out that my family, Morris, migrated from Wales to South Western Pennsylvania, setttled into Tyrone Township, Fayette County, PA and worked the coal mines here. I have been doing family history for a long time. This is one brick wall I can't break down. I want to find the Wales connection.My great, great, great grandfather's name was Samuel Morris. This is the earliest I've been able to search. Can anyone suggest books on coal miners names or photos that would have migrated into this area from Wales? My great, great grandfather Humphrey appeared as a son of Samuel Morris in 1850 PA census.Any help would be greatly appreciated.Thank you so much,Janet L. Mancini
