Barbara J. Adgate, 91, who taught elementary school in Northern Virginia for three decades, died Jan. 24 at the Sunrise senior living community in Springfield.

She had dementia, said her son Joseph J. Adgate III.

Mrs. Adgate retired in the early 1980s from Alexandria City Public Schools, where she had taught for more than two decades at schools that included Matthew Maury Elementary School and Lyles-Crouch Traditional Academy. She had previous taught for several years at Churchill Road Elementary in Fairfax County.

Barbara Lucille Jenks was a native of Earlville, N.Y., and a 1944 graduate of what is now the State University of New York at Potsdam.

Mrs. Adgate sang in the choirs at St. Mark’s Lutheran Church in Springfield and the Lake of the Woods Church, a multidenominational congregation in Locust Grove. More recently, she belonged to the Lutheran Church of the Abiding Presence in Burke.

Her husband of 57 years, Joseph J. Adgate, died in 2002. Survivors include two sons, Joseph J. Adgate III of Springfield and Gary Adgate of Carrollton, Tex.; four grandchildren; and seven great-grandchildren.
