Erica, Kathryn,
What do we want to do here with Susanna?
We say in the blue box that Ludovic had “at least one daughter probably named Mary”
WikiTree shows only Mary as a daughter.
The source attached in Geni to this person I believe is incorrect, for sure it shows the wrong photo of Ludovic!, and the dates seem to imply a generation later. I think we delete the source.
The only thing which might suggest they are siblings is that they are both shown with the same birth location in Great Tellico
