two groups with the same name

[LaneSig]

The Founders of Sigma Chi originally named our fraternity Sigma Phi, not realizing that Sigma Phi already existed in the east. Our name was not changed because of the original Sigma Phi, but because a rival fraternity at Miami (they suspected Beta Theta Pi) broke into their chapter room and stole the original ritual. When the Founders rewrote the ritual, they changed the name to Sigma Chi.

I am an alumn of the Theta Chi chapter of Sigma Chi. It sometimes causes confusion. We would often get information mailed to us as the Theta Chi fraternity.
