1950s postcard

Shamrock, Texas was named by an Irish immigrant sheep rancher by the name of George Nickel when in 1890, the Irishman applied to open a post office at his dugout home six miles north of the present town site. However, real settlement didn't begin until the Chicago, Rock Island and Gulf Railway arrived in 1902. By August, town lots were being sold at the town site that went by the name of Wheeler. However, the railroad named the stop Shamrock in 1903, and so the town returned to the original name.

Shamrock was incorporated in 1911 and the population boomed by 1926 to some 2,500 people due to oil being discovered. By 1930, the population had doubled. Gas stations, garages and cafes sprouted up all over town when Route 66 was completed.

However, when the Texas Panhandle began to see a decline in the oil industry Shamrock's population started to decrease. When, in 1984, Route 66 was officially decommissioned, the town’s population continued to wane. Today, Shamrock is home to just a little more than 2,000 residents.
