Ok here is some more information. Right before my grandma's adopted mother died she told her about a living aunt that she had in a nursing home in Fresno California. Her name was Lillan Hollinger. She has a picture of her and Lillan. She went to Fresno to visit her and she has since passed away. She passed I think about 5 years ago. Do you know Lillan? Lillian was 101 years old when she died. I'm thinking that maybe Lillan is your missing aunt? Could that be possible? My grandmother was told that Mable had 7 children that were all given up for adoption. Did you know any of Mabel children?
Wow lots of information!
