Ladies, in answer to your questions about how chapters are named, here is the fact for August 7:
At the 1909 convention, Grand Council decided to create four provinces: Alpha in the Northeast, Gamma in the Southeast, Beta in the Midwest, and Delta in the West. Sometime after 1909 but before 1922, Epsilon Province was created to govern the lower Midwest.
After Omega chapter was chartered in 1922, all chapters thereafter were named by the province that they were in, NOT in Greek alphabetical order. For instance:
While Alpha Zeta chapter was founded in 1930, Delta Alpha chapter was founded in 1923. Epsilon Alpha was founded in 1922.
Hope this clears things up!
