Thomas Garretson, 80, who used to operate a jewelry store with his wife in Waldorf, Md., for several years, died of arteriosclerosis Thursday at his home in College Park.

Mr. Garretson was born in Reliance, Va., and moved to Washington with his family when he was about 10. He peddled fish, worked as a bus driver in Washington and also managed a neighborhood grocery store. About 1935, he moved to Brandywine, Md., and there he grew tobacco.

In the late 1930s, Mr. Garretson went to work at the old Naval Gun Factory in Washington, where he was a machinist. He retired in 1950 following a heart attack.

He and his wife Virginia then opened Garretson's Jewelry Store in Waldorf, and operated it until 1975, when they retired.

Mr. Garretson was an active Mason in the LaPlata area. In the late 1930s, he headed a dance band, which included his three daughters and a son-in-law, in the Clinton area.

In addition to his wife of College Park, survivors include one son, Thomas H., of Manassas: three daughters, Helen Sears of Beltsville, Doris Brown of College Park, and Evelyn Watson of Hampton, Va.; a sister Elizabeth Knott of the Eastern Shore of Maryland; 19 grandchildren, and six great-grandchildren.
