Before my mother died, she confessed something to me she had known about for more than 50 years. Her father told her he had an out-of-wedlock daughter somewhere.
My mother never found out who or where and never wanted to. After her death, my Aunt Doris (her legitimate sister) asked if I had heard of this and expressed interest in finding her half sister.
I expect some of the cousins that turn up on my ancestry site may be related to this third sister, but I have no way of knowing at this time.
