I was posting a link on the Dampierre family (related to the Spanish Borbons) only to realize it was difficult to fit it since it was a family related to the French aristocracy
and royalty and the Spanish aristocracy
and royalty.
I'll open a thread to fit in those many other genealogy links for the aristocratic Houses of France that are a little more separated from the main royal branches.
House Dampierre Genealogical links (in French)
Maison Dampierre
As a note aside: the last Point De Vue I bought has a great article on the other families that have the title of Duke in Royal, Imperial and Republican France. I was surprised that the last title was given during the times of the current republic.
