Adele A. D. Marseglia, 87, a retired financial official for the Department of Defense and a Washington resident since 1916, died Sunday at the Washington Hospital Center after a stroke.

Born in Teano, Italy, Miss Marseglia was brought to this country, by her family as an infant. She grew up in Cleveland and in Providence, R.I., where she attended Brown University.

She worked for the old War Department and its successor, the Defense Department, from 1918 until her retirement in 1951 as chief of the finance department's allotment section.

Miss Marseglia was active in the Redeemer Italian Baptist Church here, which was founded by her father, the Rev. M. C. Marseglia. She worked with church youth and served as Sunday School superintendent there for many years.

She was a member and a former worthy matron of the Bethlehem Chapter of the Order of the Eastern Star in Washington.

Survivors include two brothers, William Marseglia of Arlington, and Vincenza Marseglia of Washington, and two sisters, Elena Morris and Abbie Maggia, both of Sarasota, Fla.

The family suggests that expressions of sympathy be in the form of contributions to the American Heart Association or to the Calvary Baptist Church in Washington.
