The original population of Retsof was mostly of Italian origin; they lived in a company town where the salt mine owned the houses and a store and maintained the small village. The Italian families lived together with a few non Italians. The others who were mostly bosses lived on the 'Avenue' in nicer houses with indoor plumbing.
In addition to the salt mine, there was a small railroad—the Genesee and Wyoming Railroad (G&W)—that took the salt to the "Main Lines" in neighboring towns. The G&W remains active today as a branch line of the Rochester and Southern Railroad.
