Louanne C. Bailey, who served on the board of trustees of the Maryland Historic Trust for more than 10 years, died Jan. 31 at her home in the St. Mary’s County community of Coltons Point. She was 81.

The cause was cerebrovascular disease, said her son John Cosimano.

Louanne Adams was born in Washington and was a 1950 graduate of the Academy of the Holy Cross. She graduated in 1952 from the old Immaculata College in Washington and later worked for a research division of the Bulova watch company led by retired Army Gen. Omar Bradley.

For three years in the 1970s, Mrs. Bailey worked at the Maryland governor’s mansion in Annapolis as an executive secretary to Jeanne Dorsey Mandel, the second wife of then-Gov. Marvin Mandel (D).

After moving in 1978 from Washington to the St. Mary’s community of Bushwood, Mrs. Bailey chaired the board of directors of St. Clement’s Island Museum and helped oversee construction of a new museum building. She served on the board of the Maryland Historic Trust from 1989 to the early 2000s.

She was a member of the Maryland Historical Society and the National Trust for Historic Preservation and a past member of the Shrine of the Most Blessed Sacrament Catholic Church in Washington.

Her first husband, John Cosimano, died in 1974 after 15 years of marriage.

Survivors include her husband of 35 years, Samuel M. “Bo” Bailey Jr. of Bushwood; two adopted children from her first marriage, John Cosimano of La Plata, Md., and Anthony Cosimano of Paamul, Mexico; five stepchildren from her second marriage, Faye Gowran of Winter Park, Fla., Samuel Bailey III of the St. Mary’s community of Avenue, Mark Bailey and Steve Bailey, both of Bushwood, and Beverly Wood of Mechanicsville, Md.; 12 grandchildren; and three great-grandchildren.
