Cornella T. Martin, 71, a former chairwoman of the Falls Church electoral board, died Tuesday at Fairfax Hospital after a stroke.

She had lived in Falls Church since 1948, when she came here with her husband, W. Edgar Martin, a specialist in biological sciences with the U.S. Office of Education.

Mrs. Martin chaired the electoral board in the late 1960s and early 1970s, serving until about three years ago. She helped reorganize the polling system in Falls Church.

She also directed the Center for Cerebral Palsy Children in Falls Church in the late 1960s. Earlier, she was a volunteer bus and bloodmobile driver for the D.C. and Fairfax chapters of the American Red Cross.

Mrs. Martin was born in Grand Rapids, Mich. She graduated from Western Michigan University in Kalamazoo and taught in kindergarten and elementary schools in Michigan before coming here.

She was a former officer of Chapter K of the PEO Sisterhood in Northern Virginia, a philanthropic organization, and was active in the Greater Falls Church Republican Women's Club.

In addition to her husband, of the home, she is survived by two sisters, Margaret Baker, of Grand Rapids, and Betty Termeer, of Los Angeles.

The family suggests that expressions of sympathy be in the form of contributions to Chapter K of PEO.
