Joyce A. Plumb, 42, a resident of the Washington area for the past 20 years who taught sewing and who was active in church and service groups, died of smoke inhalation Sunday in a fire at a Holiday Inn at Greece, N.Y., a suburb of Rochester.

Mrs. Plumb had gone to Rochester to attend the 25th reunion of her class at John Marshall High School in Rochester, her hometown. She was one of 10 persons who died in the hotel fire.

She was a graduate of Buffalo State Teachers College in New York and then taught school in Buffalo for a year.

She moved to Falls Church in 1958 and taught for a year at Lemon Road Elementary in Falls Church.

She also was a member of the Bishop Council, an organization whose members teach the Bishop method of making clothes. She had given sewing classes for a number of years and also had worked in Dee's Knit Fabrics in Arlington.

Mrs. Plumb was a member of the Faith Lutheran Church in Arlington and had been a Sunday school teacher there. She also was active in the meals-on-wheels program in Arlington.

Survivors include her husband, Kenneth, of the home in Arlington; a son, Mark, of Carmel, Calif.; a daughter, Sarah, of the home, and her parents, Mr. and Mrs. Fred Altpeter of Port Charlotte, Fla.

The family suggest that expressions of sympathy be in the form of contributions to the Faith Lutheran Church, Arlington.
