Caroline of Ansbach (1683-1737)
When the British decided to skip over all of the Catholics in the Line of Succession and settle the succession on the German family of Stuart granddaughter Electress Sophia of Hanover, Sophia's grandson George was named Duke of Cambridge and his wife Caroline of Ansbach became his Duchess in 1706. Sophia died too soon to become queen and her son became King George I in 1714 when George and Caroline became Prince and Princess of Wales. In 1727, they became King and Queen. Among their many children was Frederick Prince of Wales whom they both despised and who did not outlive them. Caroline is generally considered one of the most capable consorts. She has very involved in "helping" her husband and his Prime Minister Robert Walpole.
