Claim: Marshall Orme Wilson (born June 20, 1860) was the eldest son to Richard Thornton Wilson Sr (a multimillionaire investment banker) and his family was nicknamed the Marrying Wilsons.
Evidence: Marshall Orme Wilson (June 20, 1860 – April 1, 1926) was an American banker and prominent member of New York Society during the Gilded Age. He was the eldest surviving son born to Richard Thornton Wilson Sr. and Melissa Clementine Johnston. His father was a multimillionaire investment banker originally from Loudon, Tennessee who served on the staff of Lucius B. Northrop, the Commissary-General of the Confederate States of America and invested in railways following the end of the War. Because of Wilson and his siblings' many advantageous marriages, the Wilsons were known in New York and Newport society as the "Marrying Wilsons."
