Jennie Jerome wasn't the first American heiress to marry into a title. Lady Marianne was one of three sisters who bagged prominent Europeans. Marianne, shown here, married Arthur Wellesley after marrying Robert Patterson whose sister had married Jerome Bonaparte. Sister Louise Louisa married first Sir Felton Hervey-Bathurst, 1st Baronet Bathhurst, and second Francis Godolphin d'Arcy Osborne, Marquess of Carmarthen the future 7th Duke of Leeds. Sister Bess married Sir George William Jerningham, 8th Baron Stafford and 7th Baronet of Costessey Hall, in Norfolk, England (not Virginia). Fourth sister Emily made do with the British Consul, John MacTavish. She was Charles Carroll of Carrollton's, the longest-surviving signer of the Declaration of Independence, granddaughter. So much for all men being created equal. Jerome Bonaparte later married Princess Katharina of Württemberg.
Reuben Hart identified the sitter's home town as Baltimore and not Philadelphia.
