Earl of Castlemaine


The Earldom of Castlemaine was a title created in the Peerage of Ireland. It was created for Roger Palmer, the husband of Barbara Palmer, mistress to King Charles II. The Earl was also given the title Baron Limerick.
The title was limited to his male heirs by Barbara making it clear that the Earldom was for his wife's services to the King and not his own. As the only child officially fathered by the 1st Earl was a female, the title became extinct on his death.
