* ↑ This chapter can trace its origin to the Order of the Eastern Star Club, formed in 1922. That club formed a local sorority called Aleph Lamedh Tav in 1923. In 1927, it adopted became the local sorority named "Alpha Tau Lambda", which formed the Theta Sigma Upsilon chapter. It became the Epsilon Iota chapter of Alpha Gamma Delta with the national merger of the two sororities.

* ↑ Chapter formed from Sigma Upsilon (local), established in 1927. It withdrew in 1931 to become Delta Kappa (local), which merged with the small national Lambda Omega, which in turn merged with Theta Upsilon in September 1933. It was dormant between 1940–1946, re-established, and then went dormant again in 1952. Theta Upsilon would itself merge nationally with Delta Zeta in 1962.
