Caroline County was created in 1728, at the same time Goochland County was formed. Caroline was the wife of King George II. In 1727 he became the second king from the Hanover line that still governs England. (In 1917, during World War I, Edward VII changed the royal family's name to "Windsor" to avoid publicizing the connection with Germany.)
Caroline was intelligent. In an era where formal education for women was rare, she read often (to the frustration of her husband, who hated paperwork and avoided it even after becoming George II). Her interest in rational theology was acute, and was exploring deism at the royal court when Thomas Jefferson was a tiny child in Virginia.
She was also physically attractive and skilled in flirting. Her father-in-law, King George I, called her a devil - but appreciated her company. While she grew quite fat, she retained her fair complexion and flaxen hair. The royal couple had married for politics rather than for love, but they stayed on good terms despite their differences. She reportedly told the King, while on her deathbed in 1737, that he should remarry - but he declined, telling her with tears in his eyes that he preferred his mistresses.
Caroline knew all about the mistresses - he even wrote her long letters about the stages of his seduction of a countess in Hanover during a visit in 1735. His affairs did not seem to diminish their affection for each other. When George II died in 1660, after suffering a heart attack while sitting on the toilet, his will directed that he be buried next to Caroline and that one side be removed from each coffin so their dust could mingle in eternity.
