Essex dates back to 1883, like most of the almost forgotten traveler's rests and small communities that dot the Mojave desert along Route 66. Lewis Kingman, a locating engineer for the Atlantic and Pacific Railroad, named the water stops along the railroad route. He must have been a fan of alphabetically things, or maybe was directed to name the water stops in such a manner. So we have Amboy, Bristol, Cadiz, Danby, Essex, Fenner, Goffs, Homer, Ibis, Java, Khartoum and so on. During the early years of the small railroad stop, the primary purpose was to supply the steam engines with water.
