The Rev. Mother Agnes M. Barry, 86, who was Superior Vicar of the Society of the Sacred Heart's Washington Vicarate for 14 years before retiring in 1966, died Saturday in the Sacred Heart Convent in Albany, N.Y., following a stroke.

Mother Barry came to Washington for the founding in 1923 of the first Sacred Heart School here at 1719 Massachusetts Ave. NW, and was here when it transferred to its new address on Rockville Pike.

She taught philosophy, history, and religious studies at the Stone Ridge Country Day school of the Sacred Heart in Bethesda and resided at the Convent of the Sacred Heart here.

Mother Barry had been a headmistress, supervisor and director of novices during her years with the church. She also helped found Sacred Heart schools in Princeton, N.J., and in Miami, Fla., to teach Cuban refugees during the early 1960s.

Following her Washington retirement, she lived in Princeton, N.J., and Portsmouth, R.I., before returning to Washington in 1972. She retired to the Sacred Heart Convent in Albany four years later.

Mother Barry was born in Rochester, N.Y. She earned a bachelor's degree at Manhattanville College in Purchase, N.Y., and did graduate work at Boston College and the University of Detroit. She also studied in Rome. She entered the Society of the Sacred Heart in 1912.

A late brother, Philip Barry, who wrote "The Philadelphia Story," was the author of a play, "The Joyous Season," based on Mother Barry's life. Ethel Barrymore played the lead in the play's New York production.

Mother Barry leaves no immediate survivors.
