Aloquin
Aloquin was founded as a coeducational organization in 1905 at Ohio University. The name comes from combining the two Greek words for "Why not?". In 1910, the group split into two separate organizations, one for men, the other for women. Aloquin sorority chartered two more chapters: Ohio State University, 1914; Wittenburg College, 1915.
Ohio University's chapter affiliated with Zeta Tau Alpha in 1922; OSU's went with Chi Omega in 1919; Wittenburg's reorganized as Theta Gamma Rho in 1918.
Of the OSU chapter, Chi Omega's history recalled that the Aloquins "decided that there would be many more advantages derived from membership in a national fraternity than from a local state organization." (Ferguson, p. 188)
