The Orcas Island Historical Museum is welcoming back Lorraine McConaghy, public historian, teacher and author, during its next Historical Matinee on Sunday, July 21, 4 p.m. at the senior center.

As part of the Humanities Washington program, McConaghy has created a participatory, living theater piece in which audience members take on the   characters of ordinary settlers, territory military and administrative leaders.

Through “Territorial Voices: A Civil War Reader’s Theater,” participants will learn of the changing significance of terms like “Democrat” and “Republican,” and learn about aspects of race and slavery in Washington state over 150 years ago.
