History
The city was named for George W. Hollis, a local businessman and member of the townsite committee that laid out the town in 1898, while the site was still in old Greer County, Texas. The original plat was lost, and after a lawsuit, the town was replatted in 1903. The original business district comprised a general store opened by George Hollis and a blacksmith shop owned by James (Jim) Maylen Prock. A post office named for Hollis was established October 31, 1901. Hollis was in Greer County, Oklahoma, until 1909, when Governor Haskell divided the old county into Greer County and Harmon County; Hollis fell into Harmon County. An election was held to choose a county seat. Contenders were Hollis, Dryden, Looney, and Vinson. Hollis won the election.
