Marguerite Norma-Smith Barton, 95, a former speech teacher at the Virginia Episcopal Seminary and the College of Preachers at the Washington Cathedral, died of pneumonia Sunday at Goodwin House in Alexandria.

Mrs. Brown was born in England and trained in drama and elocution there. She was active in the Constitutional Woman's Suffrage Society in England and also appeared widely as a lecturer on various subjects and as a poetry reader. During the early years of World War I, she was a volunteer in hospitals caring for British wounded.

She moved to the United States in 1916 with her husband, Albert Edward Barton. The couple lived in Asheville, N.C. Mr. Barton died in 1932.

In 1935, Mrs. Barton moved to Alexandria. She appeared in Little Theater productions there and also taught at Virginia Episcopal Seminary and the College of Preachers. During World War II, she trained members of the speakers bureau of the American Red Cross.

About 1950, she moved to Arlington. She had been a resident of Goodwin House, which is supported by the Episcopal Church, since 1969.

Survivors include three sons, Richard W., of Arlington, Edward I., of Houston, Texas, and Victor E., of Springfield, Va.; two daughters, Jennifer Waring of Alexandria, and Penelope Paddock of Radnor, Pa.; 18 grandchildren, and two great-grandsons. Another daughter, Mrs. Armistead Maupin of Raleigh, N.C., died.

The family suggests that expressions of sympathy be in the form of contributions to the Goodwin House fund, 4800 Fillmore Ave., Alexandria.
