Did you know that the very first land grant surveyed in Stephen F. Austin’s Colony was the Sylvanus Castleman half league (2,214 acres) just a few miles from La Grange? In August 1823, even before the town of San Felipe was surveyed, Seth Ingram was sent to survey land that Castleman already lived on, keep good field notes, and return to prove to Austin and the Baron de Bastrop that he knew how to survey land, particularly along meandering river banks.
