Andrew Everett Colclough, 33, a lawyer active in Republican Party affairs, died of cancer Monday at his home in Arlington.

Mr. Colclough had served as state chairman of the Young Republicans Federation of Virginia in 1971-73 when he also had been a member of the Virginia State Republican Executive Committee.

Born in Ottawa, Canada, he came to this area as a boy. He graduated from Washington-Lee High School in 1960 and from Duke University in 1965. He received his law degree from Washington and Lee University Law School in 1968.

Mr. Colclough joined the law firm of Adams, Porter, Radigan and Mays in Arlington in 1969 and was a partner in 1974-75.

At the time of his death, he was business administrator of Christ Church at 3855 Massachusetts Ave. NW.

He was a member of the Virginia Bar, the American and Arlington Bar Associations and Phi Alpha Delta legal fraternity.

Mr. Colclough was former secretary of the Northern Virginia Lawyers Assocation. He had been active in the Arlington Jaycees and the Optimist Club.

He is survived by his wife, Virginia B. (Ginger) Colclough, and a son, Steven, of the home, and his mother, Mrs. Otho T. Colclough, and grandmother, Eula Houser, also of Arlington.

The family suggests that expressions of sympathy may be in the form of contributions to Christ Church.
