Beloved wife, mother, grandmother and great-grandmother, Dr. Maureen O'Meara Manion passed away on August 24, 2025. Maureen was born in Darien, Connecticut, on March 21, 1938, to Francis and Doris (nee Haggerty) O'Meara. She earned her undergraduate degree at Trinity College; her master's degree at Boston College, and her Ph.D. in Constitutional History at the State University of New York-Albany.
