Seems that I read somewhere that children's author Maud Hart Lovelace (Betsy-Tacy-and Tib books) was a Gamma Phi in either Minnesota or Wisconsin.
Her books are fairly autobiograpical and I remember in one book, her older sister pledges a sorority, which in actuality was Gamma Phi Beta. I don't remember what it was called in the book.
Working in a library has its advantages.
