Around 1905, representatives of the Pacific Railway and Navigation Company, interested in putting a (rail)line through from Hillsboro to Tillamook on the coast, began approaching farmers living northeast of Greenville. With the railroad coming through the Tualatin Valley a mile north of the Vandervelden farm, William (Vandervelden) and his sons, J.W. and Frank, decided to buy land around the intended railway went through Lewis Roy's place and thus, the road crossing was called Roy. The railroad went through that region in 1907, and a new church was built north of the tracks in 1908. Roy post office was established in 1907 and named for the Roy family, who were local pioneers.
