I believe this record is correct. My grandfather was called Ruby. My mother's name is Ruby also but the middle name she uses is Margaret not May, however she said she was called Ruby May and her mother's name was Julia King, although I didn't see her maiden name here. She died at the state hospital and they lived for a time in Madras Oregon. My grandfather died in Portland and I believe his death is still a cold case in police files there. My mother was born in 1915 and she is still living.
She currently resides at my sister's home in Oregon city, OR
My grandparents used other last names at times. It is interesting that her birth certificate doesn't actually have her name on it. There is no name on it at all but Julia King is listed as the mother and Ruby Hollar as the father.
