1. Originally established as Sigma Delta (local) in 1859.
2. The oldest traditional fraternities (~junior societies) at Yale named their buildings with "Hall" nicknames, by which they wished to be known on campus: Thus Theta Xi's chapter was Franklin Hall. Similarly, Phi Sigma Kappa adopted the name Sachem Hall, Delta Psi adopted the name St. Anthony Hall which spread to their entire small but old national fraternity, Chi Delta Theta (local literary honorary) established the Manuscript Society, Sigma Delta Chi (local) was renamed the Cloister Club which soon became Book and Snake. Phi Gamma Delta was Vernon Hall which later became Myth and Sword, Chi Phi was York Hall, Psi Upsilon became the Fence Club, and finally, Delta Phi was known at Yale as St. Elmo's.
