 And I mention an odd connection to the Duke of Wellington, who led the coalition forces at the Battle of Waterloo. Betsy Paterson had an older brother, Robert Paterson, who married another heiress, Baltimore Belle, named Marion Caton. Robert died in 1822, leaving Marion Caton Paterson a widow. She remarried a British peer named Richard Wellesley, the first Marquess Wellesley, who was the great-great-great-great-grandfather of Queen Elizabeth II.
