The best source of information on Philip W Croak and his children is in BIOGRAPHICAL SKETCHES, BEER'S HISTORY MCKEAN COUNTY USGenWeb atwww.rootsweb.ancestry.com/~pamckean/BeersHistory/beer.html
If you google Philip W Croak it will come up on the first page. He was the general foreman in the Buffalo, Rochester & Pittsburgh Railroad shops at Bradford, PA from 1888-1894.
Information on his parents and children too. I am also a great grandchild.
