Alpha Delta Theta Merged w/ Phi Mu
Alpha Kappa Psi fd.1904-dissolved
Alpha Sigma Delta merged with Lambda Omega who later merged with Theta Upsilon who later merged with DZ
Beta Phi Alpha joined DZ
Beta Sigma Omicron joined ZTA 1964-so some of those girls are probably still alive!
Two Chapters of Delta Sigma joined AOPi
Pi Delta Theta (an NPC member) joined Delta Sigma Epsilon in 1940-first merger of that kind within the AES
Delta Sigma Epsilon joined DZ in 1956
Iota Alpha Pi-first national started by Jewish Women in 1903. Disbanded 1971.
Phi Omega Pi-founded 1910and an NPC member-amalgamated with Sigma Phi Beta in 1933. Soon after, chapters were absorbed by AOPi, AGD, SK, and KAT. Formally disbanded in 1946 and DZ absorbed the rest of the chapters and all alumnae per an NPC request (intresting!)
Pi Delta Theta-the brain child of Sarah Ida Shaw-remember her?-formed in 1925, later merged with Delta Sigma Epsilon then with DZ
Pi Lambda Sigma merged with Theta Phi Alpha in 1952 because they were both Catholic sororities at the time.
Sigma Sigma Omicron formed in 1920, changed its name to Sigma Phi Beta in 1927.
Then merged with Phi Alpha Chi b/c of the similar principals and goals. Then was absorbed by Phi Omega Pi which was absorbed by DZ.
Sigma theta Upsilon merged with AGD.
Theta Upsilon merged with DZ in 1962-probably some of them are still alive.
I believe at one point Kappa Beta Gamma were part of the NPC and then left NPC but they are still going strong with 7 chapters and 3 alumni associations. I think they may have some interest groups too. Not sure.
