Louis XV

King Louis XV was the lover of Reinette in her later life and was dubious about the Tenth Doctor until he was saved by him from the Clockwork Droids.

When the Doctor arrived in France in 1764, it was in time to see Reinette's hearse leaving Versailles for her grave. The King gave the Doctor a letter from his mistress. (TV: The Girl in the Fireplace)
