On April 6, 1922, the degrees of the International Order of the Rainbow for Girls were first exemplified on a class of 171 girls in the auditorium of the Scottish Rite Temple in McAlester, Oklahoma. The very inception and writing of the first Ritual, and the laws governing the Order, was the work of Reverend W. Mark Sexson, a 33° Mason from McAlester, Oklahoma.

Reverend Sexson was very active in several Masonic-appendant organizations. Among his many offices, he held the titles of Most Worshipful Grand Master of a Sovereign Masonic Grand Jurisdiction (1928) and Worthy Grand Patron for the Order of Eastern Star (1925-1926), both in the state of Oklahoma.
