I've done some research on Theta Phi Alpha's Alpha chapter at University of Michigan. The Centennial History book says that in 1943 that Alpha lost its house when the government took over fraternity housing for the war. It remained on the rolls until 1948 because the alumni intended to bring the chapter back after the war when conditions were right
. However, I found the following in the "President's Report to the Board of Regents for the Academic Year 1935-1936" (Dean of Women's section)
"We had the problem of of several sororities with a larger group than they could house and of several others with too few memebrs. As a result of this situation, two sororities were withdrawn in June, 1936, the Catholic sorority (Theta Phi Alpha) and a general sorority (Delta Zeta). With the withdrawal of Sigma Kappa sorority the year before, the number of sororities was reduced to eighteen as compared with twenty-one of the peak years."
Theta Phi Alpha does not have a page in the University of Michigan Yearbook for any year after 1935-1936. *However* immediately after there were a *few* sisters who mentioned their membership in their senior description.
Additionally, it appears that Theta Phi Alpha *did* return in 1942
But again, its end was removed in the Board of Regents report for 1943
