JACKSON, ISAAC (?–?). Isaac Jackson, one of Stephen F. Austin's Old Three Hundred colonists, received title on August 7, 1824, to a league of land on the east bank of the Brazos River in what is now southwestern Grimes County, two miles below the site of Washington-on-the-Brazos. The census of March 1826 classified him as a farmer and stock raiser, a single man aged over fifty.

Another Isaac Jackson, who was born in Georgia and arrived in Texas from Ohio on December 26, 1827, settled in the Austin colony in Grimes County. He was aged thirty-two and had with him his wife, Samantha, and three daughters. He was still living in Grimes County in 1860.

A third Austin colonist named Isaac Jackson arrived in March 1830. He and his wife, Tilly, were both aged forty and came from Alabama with three sons and two daughters.
