Good News: I was able to disprove the connection to Carrie Fisher in a short time, when I couldn't locate any sources and going back two generations couldn't find any proof of my ancestress being in Virginia or a connection to the family. I contacted the WikiTree individual who had linked my ancestress to incorrect parents, asked for the sources she used to establish the parental connections, which I so hoped she would have. She didn't have any sources, so she unlinked my ancestress from the parents. I was sad to say goodbye to Carrie Fisher and her mother, Debbie Reynolds, as cousins.
The good news is the WikiTree is more accurate this morning.
