Groups that changed names
 

It is interesting to learn how many of our current day fraternities & sororities once had a name different from what we know them today. Some changed to avoid duplicating another group, others to take Greek letters, and yet others for reasons unknown. Maybe members of some of the organizations can fill us in. Here are the groups I have discovered:

Alpha Delta Pi from Alpha Delta Phi from Adelphian
Beta Sigma Psi - Concordia Club
Delta Upsilon - Equitable Fraternity - Anti-Secret Confederation
Kappa Alpha Order - Phi Kappa Chi
Phi Kappa Tau - Phrenocon - Non-Fraternity Association
Phi Kappa Theta - Phi Kappa Sigma
Phi Mu - Philomathean
Phi Mu Delta - Commons Club
Phi Sigma Kappa - T T T
Pi Beta Phi - I. C. Sorosis
Sigma Chi - Sigma Phi
Sigma Phi Epsilon - Sigma Phi - Saturday Night Club
Sigma Pi - Tau Phi Delta
Tau Delta Phi - Phi Sigma Beta
Tau Kappa Epsilon - Knights of the Clasic Lore
Theta Xi - Sigma Delta
Zeta Beta Tau - Home Fraternity

Alpha Kai Omega- Alpha Chi Omega

The previous name didn't last very long (Kai means "and" in Greek) but it was our name for a time. :)

More an evolution than an outright change, I guess, but:

Phi Mu Alpha Sinfonia from The Sinfonia Fraternity (or simply The Sinfonia) from The Sinfonia Club.

And would this one count?

Zeta Tau Alpha from ???

(Whether it counts as a change or not, it's cool enough to bring up anyway.)

unnamed social and study club -----> Alpha Phi Alpha Society ------> Alpha Phi Alpha Fraternity, Inc.

Kappa Delta was originally called Sigma Sigma but changed their name when Sigma Sigma Sigma was started at Longwood.

It is true that Kappa Delta was originally called Sigma Sigma, but we didn't change our name because Sigma Sigma Sigma was founded. Tri Sigma was founded in 1898, and KD was founded in 1897, so our name was in place before Tri Sigma's founding.

Do mergers count?

Phi Sigma Epsilon with Phi Sigma Kappa. 1985
Theta Kappa Nu with Lambda Chi Alpha. 1939

An FYI: it's Adelphean, not Adelphian. There is no "I" in our sisterhood! ;)

Didn't Tri Sigma used to be S.S.S.? Correct me if I'm wrong.

I'm pretty sure the change actually was because of Tri Sigma. The early KDs didn't want to announce their name (Sigma Sigma) until it was revealed in the school annual. But before the annual came out Tri-Sigma announced their name. SS/KD went back and changed the name of the sorority.

I'm not sure that this is covered in Ordinary Miracles but it's definitely in the older histories.

Theta Phi Alpha was refounded from Omega Upsilon and absorbed Pi Lambda Sigma.

Alpha Delta Pi changed from Alpha Delta Phi to avoid confusion with the men's fraternity of the same name.

1851 - The Adelphean Society
1905 - Alpha Delta Phi
1913 - Alpha Delta Pi
