Although Celina was not established until 1876, settlers came into the area at a much earlier date. In October 1879 a little settlement began to form a few miles southwest of the present-day Celina. John  T. Mulkey, Celina’s first   Postmaster, renamed the town after Celina, Tennessee. The railroad came through town in 1902, leading residents to relocate the main street eastward toward the tracks. The result is The Square that we know and love today. Celina has always been a small city, with a big vision!
