In 1898 Mabel Stevens (1868-) married Canadian Francis Sydney Smithers (1849-1919). Mr. Smithers started out as a banker, having joined his father’s firm of Unger & Smithers in New York.  The firm had dealings with foreign exchange, bank acceptances and commercial paper.  When his father retired, the firm was renamed F.S. Smithers & Co. and played an important role in the consolidation in 1911 of the Tabulating Machine Co., The International Time Recording Co., The Computing Scale Co. and Bundy Manufacturing Co. into one single organization which in 1924 became International Business Machines Corporation.  Smithers also served as Director of the American Bank Note Company, the North American Company, and the Milwaukee Electric Railway and Light Company.  After becoming a U.S. Citizen in 1902, his civic activities included the founding of, along with J.P. Morgan and others, the East side Housing Settlement, a settlement house in the Yorkville area of the East side of Manhattan.
