In 1889, Tucker entered the field of banking and finance, at which time he organized the firm of Walter, Tucker & Co. Upon the death in 1892 of Walter, the firm of Tucker, Anthony & Co. was organized, with S. Reid Anthony as a member.^[3] Later Phillip L. Saltonstall, Nathan Anthony and Chauncey Eldridge joined the partnership, and the firm eventually became a leader among the banking and brokerage houses in Boston and New York. Tucker retired from active business in 1924,^[2] retaining only his interests as director in a number of corporations, including the Knickerbocker Trust Company.^[4]

In 1876, Tucker married Elizabeth Foster (1856–1937), a daughter of The Right Rev. Randolph Sinks Foster, Bishop of Ohio, and Sarah Ann (née Miley) Foster.^[5] Together, they were the parents of three children:^[2]

Archibald Lionel Lindsay, second son of David Bethune, 11th Earl of Lindsay and Emily Marian Crosse,^[7] in 1900.^[8] They divorced in 1906,^[9][10] and she married Ezra C. Fitch Jr., son of Ezra Charles Fitch, president of the Waltham Watch Company, in November 1906. After Fitch's death in 1917,^[11] she remarried her first husband, Archibald, in 1921,^[11][12] before he inherited the earldom from his elder brother, Reginald, in 1939.^[13][6]
• Randolph "Ralph" Foster Tucker (1879–1971), who married Mona Louise House, a daughter of "Col" Edward M. House and Elizabeth Louisa "Loulie" (née Hunter) House.^[14] Her sister, Janet House,^[15] married Gordon Auchincloss (brother of Charles C. Auchincloss and U.S. Representative James C. Auchincloss).^[16]

George Prendergast (rector of an Episcopal parish in San Diego),^[18][19][20] and Randolph Foster Tucker Jr. (1914–1936), who died in a car accident.^[21]
