Baby Girl born late July 1967 or 8/1/1967 near Vernon CT

Searching for a girl placed for adoption, she was born approx 7/30/1967 - 8/2/1967. Her mother Carole was an unwed teen sent from Asheville NC to Vernon CT (supposed to a home for unwed mothers) in mid-July 1967. A letter written by the birth father (also my father) indicates that Carole phoned him on 8/2/23 to say the child had been born. The girl was placed for adoption. This girl and I share a biological father and I'd be elated to know more about her. I'll also be happy to share info on our father and the half-siblings she has in the Asheville NC area.
