I know for sure that TPA knows where three of our founders are buried--we went to the cemetery in Ann Arbor, Michigan, where Katrina Caughey Ward, Camilla Ryan Sutherland, and May C. Ryan are buried and put white roses at their graves this past July at our Centennial Convention. It was SO moving and powerful!
I believe there was talk of Otilia Leuchtweis O'Hara being buried in New York state, but I am not sure about that.
Aside from the flowers we put, though, there was no mention of Theta Phi Alpha.
