John Pugh IN PA

our Pughs come from the Columbia and surrounding counties. John was born in 1843, married Dianna Scott b. 1845 d.1878. 2 sons Robert Scott b abt 1870 & George F b soon after since Dianna passed in '78. Dianna & George are buried in Highland Cemetery, Lightstreet, PA. George died in 1892. I think John was an iron ore miner. But know nothing else about him. Any help would be great. Thanks
