GROVE CITY — The Grove City College history department will present Carl Robertson and Diane Crews of the Providence Plantation Foundation at 7 p.m. Wednesday in Sticht Auditorium in the Hall of Arts and Letters on campus.

The Providence Plantation, near Evans City, provides actor-interpreters in period attire who portray significant 18th century characters on the upper Ohio Valley frontier.

The program will include audience participation and interaction, along with a question-and-answer session at the end of each interpretive presentation.

Robertson will play Christopher Gist who served as a guide for George Washington when he explored Western Pennsylvania in the early 1750s. Gist served as an agent of the Ohio Company and piloted Washington’s first official mission in the area in 1753.

Diane Crews will portray Peggy, a slave, who was taken in a western Virginia Indian raid and then “rescued” from the Indians. Colonel Henry Bouquet’s army brought Peggy to Fort Pitt where she debated whether to flee back to the Indians to gain her freedom, or return to Virginia and possible re-enslavement.

Admission is free.
