I am trying to get more information about my great grandfather and his father..

William MASON (? to 1892) who married Agnes Purviance McClelland ofFranklin, Venango Co. Children: James Bryden Mason (about 1865 in Tionesta PA to 1935 Buffalo NY;
a druggist in Buffalo NY), Robert Lee Mason (who I believe became a banker), William Mason (b/ 1867 d. 1947; went to England and ran a business there through W.W.II), Alfred Gilmore Mason, Annalana Mason (b. 1860). So far I
have discovered a William W. Mason, Esq referred in papers about the McClelland family, and a William W. Maosn on the list of lay officers for the Protestant Episcopal Church (source: Beers History of McKean Co.), and a William Mason listed as a private in the 42nd Regiment, Company I from
McKean Co.. In the Beer's source I also saw a Robert Lee Mason was a cashier and teller in a Bradford Bank during the 1870s.

James Bryden Mason was my great-grandfather. Scott Bryden Mason, his son was my grandfather who married Marie Katherine Clark of Watkins Glen NY. Their children were Hadley Currie Mason and James Burch Mason (my father).

I need to confirm this information. Any suggestions on how this could be done and any more information about this family would be appreciated
