The city of Grand Prairie was first usual as Dechman by Alexander McRae Dechman in 1863. He based the publicize of the town on vast Prairie, Ohio. Prior to then, he resided in Young County near Fort Belknap. The 1860 U.S. Federal Census—Slave Schedules shows an A McR Dechman as having 4 slaves, ages 50, 25, 37 and 10. Dechman learned that he could trade his oxen and wagons for house in Dallas County. In 1863, Dechman bought 239.5 acres (96.9 ha) of land upon the eastern side of the Trinity River and 100 acres (40 ha) of timber land upon the west side of the river for a broken-down wagon, oxen team and US$200 in Confederate money. He tried to pronounce a home on the property, but ran into difficulties, so he returned to his associates in Birdville past joining in the Civil War. In 1867 he filed a town plat with Dallas County, consisting of 50 acres (20 ha).

After the war, he returned to Birdville for two years previously selling that farm in 1867 and upsetting to Houston, where yellow fever broke out, causing the relations to reach a decision in Bryan. In 1876, Dechman traded half his “prairie” property to the T&P Railroad to ensure the railroad came through the town. The railroad named the depot “Dechman”, prompting its namesake to relocate his home from Bryan to Dechman. His son Alexander had been buzzing in Dechman and on the go a trading pronounce and farm. The first church in the Place was the fine Hope Cumberland Sabbath School, established in 1870 by Rev. Andrew Hayter. The church was unconventional renamed West Fork United Presbyterian Church and remains an active church.

The first U.S. post office opened in 1877 below the name “Deckman” rather than “Dechman”, because the U.S. Postal Service couldn’t entrйe the writing upon the form completed to entry the say office. Later that thesame year, after the Postal Service had adopted the “Deckman” name, confusion resulted from the T&P Railroad designation “Grand Prairie”. This proclaim was based upon maps drawn from a propos 1850 through 1858 that labeled the area between Dallas and Fort Worth “the grand prairie of Texas”. In order to calm the confusion, the Postal Service named the say office “Grand Prairie”.
