I am trying to find a record for my great-grandmother, Mabel L. Walker, born December 1, 1907 and died August 8, 1988. She was born in Oklahoma and was adopted, but I don't know anything about her birth or adoptive parents or if she spent time in an orphanage. Her biological father was a Walker, so she would have been adopted under this name. She also was part Indian, so she may have been born or lived on a reservation. I am told that she was sent off as a maid when she was a girl and lived with her adoptive parents until she married Isaac Ketcher at the age of 18. If anyone could find any records of her in an orphanage, it would be of great interest to me.
