Researching my blood great-grandfather who I have no information on. My grandfather, Arthur G Bates born 1911. Mother was Clara Bates (or shoeman or schuman or variant)Catt. census of 1920 has the following, I can't find any information for my grandfather's true father. My grandfathers death certificate lists Osterstuck as the father, clara (last name unknown) as the mother.

I don't know where my grandfather was born. A kind person suggested I write for the original SSN registration info. Hoping I can find something out here that someone might know. Any suggestions would be appreciated. I've hit the brick wall.

Earliest record of my grandfather:

1920 Cattaraugus/Olean War 9/District 84 William J Osterstuck 23, Clara 39 PA NY NY, Arthur G stepson 8 NY NY NY

(I'm fairly certain that Clara was 29, not 39)
