Kappa Alpha Theta - 1891-1944/1978
Kappa Kappa Gamma - 1892-1944/1978
Pi Beta Phi - 1893-1897/1905-1944/1978
Delta Delta Delta - 1909-1944/1984
Chi Omega - 1915-1944/1990
Alpha Epsilon Phi - 2007
Delta Gamma - 1887-1944/1979-1999
Alpha Phi - 1899-1944/1978-? (We did recolonize but were unsuccessful a 2nd time around)
Gamma Phi Beta - 1905-1944/1978-1992
Alpha Omicron Pi - 1910-1944
Sigma Kappa - 1915-1930
