Ceremonies will begin at Go-Art, 201 E. Main St.

Nicole Walter of the William G. Pomeroy Foundation, the organization that funded the marker, will speak briefly. Her remarks will be followed by those of Larry D. Barnes, Batavia city historian. Barnes will present a biographical sketch of Trumbull Cary and outline the history of the mansion.

Afterward, the event will move to 211 E. Main St. where Sallie Fogarty, a great-great-great granddaughter of Trumbull Cary will unveil the marker. The mansion was built in 1817 and torn down in 1964.
