An old thread, but it is the only reference to Devonshire CC in San Carlos, CA that I have found on this site.
Around 1924, a number of "live and play" communities were started on the peninsula. Devonshire Estates was one of these, as was the Monroe, Lyon and Miller development which housed the Belle Monti CC (which started as Belmont CC). Of interest is that these two projects were the only work of Willie Dunn in the state of California.
A. V. Macan was engaged in 1925 to report on Devonshire, with Sam Whiting also paying the site a visit that year.
Also in 1925 it was reported that Willie Locke was laying out a new 18 hole course for Belle Monti with later reports indicating the work was completed by Tom Nicoll.
Dunn had moved to California in 1920 to open a golf school in San Diego. He seems to have disappeared from the scene at Devonshire and Belle Monti soon after the initial work started. We know a lot about Dunn's early career as one of the pioneering architects in the United States, but we don't know much about the rest of his career.
Neither course would survive very long.
