According to "Seventy Years in Norton County, Kansas" by D. N. Bowers, "Dellvale was platted as South Oronoque by John K. Gray and Pheobe E. Gray, his wife, on September 18, 1888 and filed for record on September 18. The Rock Island Railroad went through here in 1888, and as trading centers were being established about ten miles apart, John M. Gray gave ten acres on the west side of the road, and Jim Huff the same amount on the east side, since this spot was approximately 10 miles west of Norton. Frank Gilder moved a building here from Lenora and put in a stock of general merchandise. Emereth Wray, who came here in 1879, was the next in line. He was followed by Andy Maxwell, who served the community until his retirement in 1919. He lives with a son in Cheyenne, Wyoming at the present time. M. A. Davis, whose father came here in 1878, took over from Mr. Maxwell and continued until he moved his interests to Rexford. In 1926, James McMullen established a business, which he continued until his death in 1937. M. A. Davis is again in business here in the store and elevator, and his son, Dale is the present postmaster. Sam Paxton operated the first and only hotel in Dellvale, which was regularly patronized by Rock Island train crews for more than twenty years." ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ According to Kansas Post Offices by Robert W. Baughman, Dellvale post office was established in 1890 and the first postmaster was Frank E. Gilder. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "The History of the Early Settlement of Norton County, Kansas" by F. M. Lockard says that Emereth Wray was appointed postmaster at Dellvale by President Harrison. Benjamin Harrison was elected in 1888, so Wray's appointment must have been between 1889 and 1893. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The 1916 Historical Edition of the Norton County News says, "Dellvale, a village in Leota township, is on the Chicago, Rock Island and Pacific R. R., eight miles southwest of Norton. It has a money order post office with two rural routes, a telegraph and express office and a grain elevator; according to the last census it had a population of 31. Mr. Maxwell runs the general store."
