I am looking for any information on my grandfather Frank Wojciechowski who was born abt. 1880 in Rypin, Poland. He emigrated, probably with siblings, possibly with parents, date uncertain but possibly before 1900, to United States, settling in Pittsburgh, PA. area.
He married Frances Treder, (alternate spellings may be Trejder and Trader)and they had 11 childlren. He worked in coal mining and died Oct. 13,1924, when a piece of slate fell from a roof on him. The mine was the Brier Hill Mine in Redstone Township, Fayette County, Pa.
In particular I am looking for his parents, names dates of birth, places of births,etc. and anything further back in his ancestry as well as his wife's ancestors. Anything would be helpful.
