Elizabeth D. Horne, 68, a longtime resident of Bethesda and Chevy Chase who was active in church and volunteer organizations, died of acute renal failure Friday at Suburban Hospital.

Mrs. Horne was born in Vermont and lived in New York state before coming to this area to attend college and has lived in Bethesda for the past 40 years. She graduated from George Washington University.

She has been a member of the Chevy Chase Presbyterian Church for the past 50 years, where she had sung in the choir, taught Sunday school, and been active in the women's fellowship class.

Mrs. Horne was a charter member of the Bethesda-Chevy Chase branch of the American Association of University Women and had been chairwoman of the AAUW Inter-Branch Council of Montgomery County.She also was a past president of chapter K of the PEO sisterhood and served on the board of directors of the YWCA of Washington.

Survivors include her husband, Robert C. Home of Bethesda: a daughter, Shirley H. Martin of Annapolis; a son, Robert C. Jr. of Upper Marlboro; her mother, Arletta S. Rudd of Florida, and one grandchild.

The family suggest that expressions of sympathy be in the form of contributions to the endowment fund of the Chevy Chase Presbyterian Church.
