Context paragraphs:
James E.B. Austin: James Elijah Brown Austin (October 3, 1803 – August 14, 1829) was a Texian settler and brother of empresario Stephen F. Austin, "The Father of Texas."  Counted also as one of the Old Three Hundred, he is listed in Spanish and Mexican records as "Santiago E.B. Austin".  James and Stephen F. Austin are both brothers of Emily Margaret Brown Austin.

Stephen F. Austin: Stephen Fuller Austin (November 3, 1793 – December 27, 1836) was an American empresario.  Known as the "Father of Texas", and the founder of Texas, he led the second, and ultimately, the successful colonization of the region by bringing 300 families from the United States to the region in 1825.

Fort Bend: Fort Bend was a blockhouse built in a large bend of the Brazos River in what is now Fort Bend County, Texas, to provide protection against Indian raids.  It was erected in November 1822 by several members of Stephen F. Austin's Old Three Hundred, including William W. Little, Joseph Polley, William Smithers[Smeathers], Charles Beard, Henry Holster and is described as a "little log shanty."  The location was reportedly selected by Austin, and a settlement soon grew up around the post.  As the site provided one of the more favorable fords of the Brazos River, it became important during the Texas Revolution.  The Fort Bend crossing was briefly defended in April 1836 by a rear guard detachment led by Wiley Martin.  After Martin was maneuvered out of the position Gen. Antonio López de Santa Anna transported a portion of his Mexican army across the Brazos at the crossing.  After Santa Anna's defeat at the battle of San Jacinto the site was used briefly by the Texas army.  Troops under Thomas Jefferson Green, who were in pursuit of retreating Mexican forces led by Gen. Vicente Filisola, halted for a short time in mid-May 1836 at Fort Bend.  Because Fort Bend had been the center of activity in the area its name was given to the county when it was established in 1837.  The next year nearby Richmond, Texas was selected as the county seat and soon absorbed the smaller Fort Bend settlement.  In 1936 the Texas Centennial Commission erected a monument to commemorate Fort Bend's role in the Texas Revolution.
