A mail service was established, and after rejecting several names for the nascent town (including naming it in honor of then-President Millard Fillmore), residents suggested the name Plano (from the Spanish word for 'flat') in reference to the local terrain, unvaried and devoid of any trees.
Facilities such as a sawmill, a gristmill, and a store soon brought more people to the area. Settlers came to the area near present-day Plano in the early 1840s. See also: Timeline of Plano, Texas Plano, Texas in 1891.
