Donnell family.

James C. Donnell (1854-1927), his son, Otto D. Donnell (1883-1961), and grandson, James C. Donnell, II (1910-1984) each served as president of the Ohio Oil Company of Findlay, Ohio. Founded in 1887, the company was taken over two years later by John D. Rockefeller's Standard Oil Company. By Supreme Court action in 1911, Ohio Oil and Standard Oil were broken up, and Ohio Oil again became independent under the first James Donnell. He was president from 1911 to 1927 and Otto was president from 1927 to 1948. In 1962 the Company's name was changed to Marathon Oil Company.
