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 had been born in England.

He and his wife Henrietta lived in August and Emily Turner Wexelberg's boarding house at 2111 Indiana Avenue in Chicago, IL's south side in 1880. It was several blocks east of what is today the Englewood neighborhood.

During 1892 and 1893, Willcox resided on the southeast corner of Prescott Place and Hamlin Street on Lake Union in Seattle. (See R.L. Polk Directory Company's Seattle, WA, City Directory, 1892, p. 927 and R.L. Polk Directory Company's Seattle, WA, City Directory, 1893, p. 944.) The 1893 directory noted that he lived on "Mansion southeast corner of Hamlin."

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.

He had a son Frederick P. Willcox, who resided at home in 1893. (See R.L. Polk Directory Company's Seattle, WA, City Directory, 1893, p. 944.)
