Helen A. Sharp White, 84, a life-long Washington area resident and the mother of 18 children, including six sons who served in World War II, died of a cerebral vascular accident Wednesday at Prince George's General Hospital.

Born and reared in Washington, Mrs. White attended Maurey and Edmonds elementary schools here and graduated from old Business High School. In 1917, she married William A. White, an employe of the Treasury Department's Bonds and Currency Division. She and her husband reared 10 sons, eight daughters and a nephew, Jules F. Morel.

In World War II, six of the sons, and Mr. Morel, served in the armed forces. Because of this and the fact that the entire family was involved in the war effort -- their photograph was used to promote the sale of war bonds and defense saving stamps -- the family was featured in newsreels and in news stories in local newspapers and national magazines, including Life.

All of the men returned safely from the war. Today, 16 of the children, and Mr. Morel, survive. A daughter, Alice M. Sweadner, died in 1958, and a son, Robert B., died in 1972.

After the death of her husband in 1966, Mrs. White lived with a daughter, Dorothy J., in Landover Hills. She was a member of Holy Comforter Catholic Church in Washington and was active in its Women's Sodality.

Besides her daughter and Mr. Morel, survivors include nine sons, William M., Paul A., James P., and Francis S., all of Silver Spring, John J., and Michael P., both of Vienna, Theodore F., of Riverdale, Bernard A., of Landover Hills, and Thomas X., of Greenbelt; six other daughters, Ellen R. Handley of Washington, Mary C. Lockman of Rogers Heights, Md., Catherine A. West of Oxon Hill, Marie R. Helm of Arlington, Theresa H. Dobson of Vienna, and Sara K. Ruschaupt of Tel Aviv, 59 grandchildren and 29 great-grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to St. Ann's Infant and Maternity Home in Hyattsville.
