I was not able to get the message sent via Ancestry as I am not a member. Don't know if it was different than what you posted here (or if it was just a duplicate announcement).
My primary interest is in descendants and relatives of Harriet as it is she through whom I have a connection. She is my great-grandmother's half sister, but the children by the two marriages apparently never had much contact with or knowledge of each other, so I'm trying to fill in the gaps both with individual's data and family stories.
