Cardon, Spain & France

The following was posted by an anonymous reader as a comment on my "French Origins?" posting at LiveJournal (my previous blog location).

I have been looking into yet another branch of the Cardon famille which has its roots in Spain and are known to have crossed into France and some setlled in and around Lyon area. The Famille name in Spain was Folch de Cardonne and lived in the Catalogne area in the Chateau (Castell ) D'Arbcea which is now open to the public. This famille was first recorded in the chateau in 1158, they held the title of Comte de Carrdonne. About 1475 - 1500 they became the Duc de Cardonne: the first to hold this title was Joan Ramon Folch IV.
