From the
www.alphadeltapi.org website (under Potential Members --> Heritage) which also has pictures of five of the six founders:
"Founded on May 15, 1851, Alpha Delta Pi is the oldest secret society for college women in the world. Established at Wesleyan College in Macon, Georgia, the first college chartered to grant degrees to women in the world, the story of Alpha Delta Pi is a remarkable one and it all began with one girl's dream.
Eugenia Tucker was just sixteen years old when she left her family home in Laurens County, Georgia, to enter Wesleyan College. Before the end of her first year she would establish the first sorority in the world.
When Eugenia Tucker decided to form a society, her dearest and most admired friends were asked to join her. She listed them in her journal as: Ella Pierce, daughter also of a Bishop; Octavia Andrew, daughter of the Bishop; Bettie Williams of South Carolina; Sophronia Woodruff; and Mary A. Evans, daughter of a useful and beloved pastor of Macon Mulberry Street Methodist Church for several years."
What's also important to know is that the sorority was founded as the Adelphean Society at Wesleyan in 1851 (Phi Mu founded as the Philomathian Society there in 1852, ), that they decided to go national in 1904 and added their Beta Chapter at Salem College in 1905. The changed their name to Alpha Delta Phi in mid-1905, joined NPC in 1909, and changed the name to Alpha Delta Pi in 1913.
