David Choate Jr. was born in Louisiana in 1811. He moved with his family to Texas and later joined a group of Beaumont volunteers and fought in the Battle of San Jacinto on April 21, 1836. Choate received bounty for 320 acres of land for serving in the army and 640 acres of donation land for fighting in the Battle of San Jacinto. These lands were surveyed on the north side of Pine Island Bayou, where in 1856 he founded Concord, originally part of Jefferson County. It had a well-known ferry crossing that connected Beaumont to Points North. Choate and his wife, Mary (Coon), contacted the Orange County surveyor to lay out the town in 1858. Hardin County was created in 1858, carved out of Jefferson, Liberty and Tyler counties. The town of Hardin was created as the county seat in 1859. It was located on the Concord to Woodville road. Concord became the southern shipping point for steamboat traffic on the Neches River, bringing farm products and lumber from Hardin, Tyler and Jasper Counties into Beaumont. At its peak, concord had 300 residents. Concord and the town of Hardin thrived from steamboat traffic and shipping. With the completion of the railroads from Beaumont to Rockland, the town of Concord passed into history as steamboats were no longer needed. Concord was abandoned in 1880 but had served its purpose as a steamboat stop. David Choate Jr. died in Concord in 1879 and was buried in Leatherwood Cemetery, located on the David Choate survey. His widow died in 1909 and is also buried in the cemetery.
