I don't know why he didn't but it was probably a good thing.Their mom Catherine or Katy (Sangwin)Keller, died in child birth in her 50's. So Calvin was just a baby when all the kids went to the orphanage. Norma died while in the orphange reportedly from a botched abortion. He got mom and Fern out at age 18 and they moved back to Eureka, Montana with him. Bob and Lynn also moved back there and lived there until they passed away.Ruby the oldest sister lived in Helena until she died. Percy was a real S.O.B. I don't remember what year he died. We believe we are of Crow Indian decent but I have not been able to track our Grandmother's history back far enough. Not enough time. What I know is, our Grandmothers maiden name was Sangwin, Her parents were Susan and Samuel Sangwin. The census reports she was born on the Crow Reserve. On some of the Cenus's she is reported as Blood or Indian, on others as white, this was sometimes done because of the negative feelings toward Indian people.
