About the Σ Chapter
Family Tree
All pledges are assigned a "big brother" when pledging our chapter. The "big" acts as a mentor through the pledging process. When a a pledge becomes a member, they will act as a "big" for someone in the next pledge class. Our family tree is based on who had who as a "big".
How to read the tree
The boldface names are the "roots" of the tree. These are the earliest known members who can be traced to current lineage. Their littles are indented once, their grandlittles twice, and so on. Italicized names indicate a Sigma member who has a big that was initiated in another chapter.
