Alice Biddle Grey, 87, who was active in area Episcopal Church affairs, died of a heart attack Wednesday at a convalescent home in Riverside, Calif. She had moved there two years ago.

Mrs. Grey was born on a farm on the grounds of the U.S. Soldiers' Home here. Her mother died of tuberculosis when she was a child. She and her sister and two brothers grew up in an orphanage then operated by St. John's Episcopal Church on Lafayette Square. Their father paid for their care.

She left the orphanage at the age of 16 and shortly after married Irving M. Grey, whom she had met there.

He was associated with the Carnegie Institution here for 37 years before his retirement in the late 1940s. He then became known as the poet laureate of the Democratic National Committee. He died in 1955.

Mrs. Grey had been a member of St. Stephen and the Incarnation Episcopal Church and St. Paul's Rock Creek Parish. She was active in the Daughters of the King, an Episcopalian group, and in the Eastern Star.

She is survived by two sons, Stephen B., of Arlington, and William J., of Riverside, Calif.; two daughters, Alice Wagner, of Fort Meyers, Fla., and Sarah Elizabeth Grey, of Washington; a brother, Norton Biddle, of Arlington, eight grandchildren and 10 great-grandchildren.
