I am from South Dakota, Aberdeen, my Grandfather's name was Lincoln Ion Fuller Easterby, born in the late 1890's. I know he had brothers and sisters, but not sure if any of them were Silas.At one point in my life I was living in Puyallup, Washington and met a cousin name David from OK. His grandmother was married to a Sheppard (2nd marriage I believe).
I have an Uncle living in South Dakota at present his name is Nels. There are two sisters living there also, Adilene and Marilyn. A Brother James died in Kansas in the the 70's.
My Father Elmo and his brother Severt are living in Washington state still.
