One of my ancestors was a married to the daughter of Adelaide Kate Davy.
He was a moderately well-known scientist and newspaper articles made a big deal of his wife's connection to the very famous scientist Sir Humphry Davy.
However, I have never found her mother on the Davy trees and can't prove that they are relations. Do any of you have her on your trees?
