2016 Note of Caution: Wikipedia page for this George Downing states that his parents were Sir George Downing, 2nd Baronet, and Lady Catherine Cecil while the Wikipedia page for Lady Margaret Cecil (pos a sister?) (aka Countess of Ranelagh) [1] states that she was the mother of this George Downing. More research needed.
