On Friday, May 6 at the Glen Arbor Township Hall, the Empire Area Heritage Group will present “The Boizard Letters” at 7 p.m. A half-hour video presentation will feature recollections of Julia Dickinson and Joan Bolton, who found over 100 letters written before, during and after the Civil War between a husband in the service, and his wife who stayed behind in Glen Arbor to fare for herself and her small child.
