Location within Creek County, and the state of Oklahoma
In 1908, James M. Thomas, a native of Shamrock, Illinois, moved to this area and opened a store. He named the post office that he established on July 9, 1910 in honor of his home town. Between 1915 and 1916, the Sapulpa and Oil Fields Railroad (later the St. Louis and San Francisco Railway) built a line northward from Depew to Shamrock. In 1916, theAtchison, Topeka and Santa Fe Railway constructed a line that connected Shamrock andDrumright. The railroad bypassed the town by three-fourths of a mile, so the citizens moved their businesses closer to the railroad. This developed Shamrock as a major shipping point for oil field equipment and crude oil. The town adopted an Irish theme, with streets named Tipperary, Dublin, Killarney, Blarney, and Cork.
The board of trustees voted to dissolve the town in June 2010, and it has been placed in receivership with Sapulpa attorney Bill Sellers.
