I am researching the Weston surname in Western or Central PA.

John Raymond Weston (1906-1979) is my Great Grandfather. He was born in PA and died in Greensburg, Pa. He was a Coal Miner who lost his leg in a mining accident. Where can I find mining records?

His father, my GG Grandather from what I found is John William Weston born 1884 in Clearfield, PA.

My GGG Grandfather according to the 1900 Census is Curtis W. Weston who married Arminda Jane. (Who in later censuses goes by Jane) In 1910 they moved from Cambria Co. PA to Indiana County, PA-If I am right.

I can't seem to find anything further. Can anyone guide me in the right direction? I can't find any earlier censues of the Weston side as well as birth, marriage or anything.
