In 1848, John Stanton Williams (c. 1810-1876) and Stephen Barker Guion (1820-1885) formed the New York firm of Williams and Guion to operate the Black Star Line of sailing packets on the Liverpool-Queenstown-New York route.
A number of international conferences and committees were held in 1866, 1872, 1887, 1889, and 1891 all of which left the designation of sea lanes to the principal trans-Atlantic steamship companies at the time; Cunard, White Star, Inman, National Line, and Guion Lines.
