Elizabeth Mary Hayes Quinlan, 81, a former secretary at the National Institutes of Health who helped make her birth town in Ireland the sister city of Annapolis, died Oct. 6 at home in Silver Spring of renal failure. She lived in Annapolis from 1968 to 1997.

Through her active membership in the Annapolis chapter of the Ladies Ancient Order of Hibernians in America, Mrs. Quinlan had a "significant influence" earlier this decade in forging the tie between Annapolis and Wexford, Ireland, the Annapolis mayor's office said.

Mrs. Quinlan moved to Silver Spring two years ago.

Mrs. Quinlan was born in County Wexford but grew up in Alberta, Canada. She later worked as a secretary in Ohio before moving to the Washington area in 1945.

After spending time as a homemaker, Mrs. Quinlan was a secretary at NIH from the late 1950s to the late 1960s.

Mrs. Quinlan was a member of St. Mary's Catholic Church in Annapolis.

Her husband of 18 years, William Welty, died in 1964.

In 1968, she married William A. Quinlan, a former member of the Montgomery County Board of Appeals.

She is survived by her second husband, of Silver Spring; two daughters from her first marriage, Patricia M. Welty of Bethesda and Elizabeth M. Wierdak of Rockville; three stepsons from her second marriage, William A. Quinlan Jr. of Derwood, John R. Quinlan of Sawgrass, Fla., and Michael A. Quinlan of Marco Island, Fla.; 11 grandchildren; three great-grandchildren; and one brother.
