What stands out about Omaha’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
This area of Texas had been lightly settled under Spanish and Mexican rule. It was primarily settled after annexation by the United States by migrants from the South, many of whom arrived before the American Civil War. In that period, farmers had established cotton plantations. It was also an area of pine forests.
