Lucy Gaddy does not have accurate parent information.
Find a Grave does not pretend to give any sources for parents. https://www.findagrave.com/memorial/176763598/lucy-gaddy
Family Search profile does not seem to have consistent or realistic sources. Some are noted after her death such as NC Birth and Christenings 1866- 1964. I think that is where the name "Sarah Watson" comes from.
My thoughts until I find something new to change them - We don't know who her parents are and may need to cut until proof can be offered. Put placeholders on parents and hope for some new information. I think this needs a curator to weigh in.
