Roger Palmer, Earl of Castelmaine, was born September 3, 1634 in Dorney Court, Buckinghamshire, England. He was the son of Sir James Palmer and Catherine Herbert. Roger married Barbara Villiers (Duchess of Cleveland), April 14, 1659 in London, England. Roger Palmer passed away 1705 in Oswestry, Shopshire, England.
History of Parliament writes:
Although low of stature, unprepossessing in appearance, and of modest wealth, Palmer was accepted in marriage by the most beautiful nymphomaniac of her day, who, in consequence of a teen-age affair with the 2nd Earl of Chesterfield, required a complaisant or gullible husband. On the eve of the Restoration Charles II was told of his ‘gay wife, great expenses and slender fortune’, and, anxious to improve his acquaintance with the first of these handicaps, wrote to thank him for his signal services to the royalist cause, though it is not known what they were.
It seems unlikely that he was the father of any of his wife's numerous children.
Sir Roger was created Earl of Castlemaine then moved to Ireland with a grant of Castle Lackin plus significant land in Co. Mayo during 1684.
