irishpipes, from old Baird's Manuals, I've found there were at least four (there might be more that I don't know about):

Beta Sigma Omicron, 1927-41

Beta Phi Alpha, established there in 1923, not sure when it closed -- maybe in 1941 when Beta Phi Alpha merged into Delta Zeta

Phi Omega Pi, established there in 1911, not sure when it closed.

Theta Upsilon, established there 1923; briefly inactive 1940-46, then active again until 1962, when Theta Upsilon merged with Delta Zeta (overlapping chapters at Illinois)

Iota Alpha Pi disbanded its IHQ in 1971
