Hey, Guest, JB Goode,
If you return to read this, my great grandfather, Thomas Matthew Loughney and at least one of his sons, also named Thomas, were hard coal miners as well in Pittston, PA. That was back starting around the 1870s. Another of my great grandfathers, Peter Donnelly, started out as a miner, then moved up to finally being an engineer for Pennsylvania Coal Company (forefunner to the Pennsylvania Railroad), also in Pittston, PA. When were your grandparents mining in Pittston?
One of my grandfathers, Patrick Meehan, started his employment, at about 6 or 7, as a breaker boy, the official job classification was slate, for a coal company in Jermyn, PA (north of Scranton).
