These groups engaged in agriculture and traded with Spanish and French at trading posts along the Red River. This resulted in the establishment of trading posts at Preston Bend on the Red River, Warren, and Pilot Grove during 1836 and 1837.After the establishment of Peters Colony in the early 1840s, settlement near the Red River became more rapid, and Grayson County was created from Fannin County by the Texas State Legislature on March 17, 1846. The county seat, Sherman, was also named by the Texas State Legislature.
