In 1415 the family was finally acknowledged as a part of the French nobility when Thomas Alberti - or d'Albert as they were known in France - purchased the Luynes. They further cemented their place in the aristocracy when Honoré d'Albert de Luynes fought on the side of Henry IV which meant that a lasting connection with loyalty to the Crown was established.
From there on, the family moved easily in the highest circles in the land. Charles Albert became a favourite of Louis XIII and has been rumoured to have been his lover. His brother married a noblewoman and was created Duc de Chaulnes - finally removing any shred of a doubt of the family's belonging to the nobility. Their last brother also became a Duc through his marriage to the Duchesse de Piney.
The branch of Piney-Luxembourg died out in 1697.
