Northern Virginia delegates had litigated the voting apportionment case Davis v. Mann, and the United States Supreme Court ruled in their favor in 1964.
In the subsequent reapportionment, Alexandria gained a seat, so Galland served alongside conservative James M. Thomson, whose father-in-law was U.S.
Senator Harry F. Byrd, one of the principal architects of Massive Resistance against the Supreme Court's school desegregation decision in Brown v. Board of Education.
Described as a "four foot, 11-inch dynamo" who "probably weighed less than 95 pounds soaking wet," by a later successor, state senator Patsy Ticer, Galland was active in the League of Women Voters and Association of American University Women, and later became the first President of Alexandria Senior Services (1968) and of the Alexandria Community Y (which became the Campagna Center)(1971–74).
Galland was also active in the Alexandria Parent Teacher Association, St. Paul's Episcopal Church, Church Women United, the Business and Professional Women's Club, WETA, Planned Parenthood, the Hunting Creek Garden Club, the Salvation Army Auxiliary, Urban League, Association for Childhood Education, the Northern Virginia Association for Retarded Children, Human Relations council, Washington Area United Givers Fund, Alexandria Red Cross, and the National Symphony Women's Committee.
