Willcox authored the 1884 architectural treatise on ecclesiastical design: Hints to Those Who Propose to Build; also a Description of Improved Plan and Construction of Churches, (St. Paul, MN: Pioneer Press Pub. Co., 1884).

The well-traveled Willcox worked in New York, Chicago, Nebraska and Minneapolis-Saint Paul before landing in Seattle, WA, to practice architecture. He moved to Los Angeles, CA, c. 1893, during the Depression of that year, like John Parkinson (1861-1935), Elmer Fisher (c. 1844-1905) and a few other leading Seattle architects. He died in a veteran's home in the Northern CA town of Yountville at the age of 96.

While in Los Angeles, CA, in 1896, Willcox became active in local Republican Party politics. He was named to be (1 of 73) Vice-Presidents of the McKinley Club of Los Angeles in that year. In 1898, Willcox sued the 1st Baptist Church of Los Angeles for failing to pay for his services.
