Pueyrredón (surname)
The Pueyrredón surname has its origins in 13th century France. Initial variants were Puyredón, Puiredón, Puecheredón and Puitredón. The etymology comes from "Podium Rotundum". "Puy" means mountain or hill, and "redón" means round. So, Pueyrredón" would mean "rounded hill". It was used at the Languedoc to name "puy" any lonely mountain. As such structures were strategically useful for the construction of castles, many royal families had names with the "Puy" element in them.
