John McCroskey, one of Stephen F. Austin's Old Three Hundred colonists, was elected third lieutenant of a company of militia at San Felipe de Austin on July 10, 1824. On August 26, 1824, he received title to a labor of land in the area now in Austin County and a league of land on Cedar Lake Creek five miles south of Brazoria in what is now Brazoria County. In January 1827 McCroskey met with other settlers at the home of Bartlett Sims to adopt resolutions of loyalty to the Mexican government and condemn the Fredonian Rebellion. In September 1829 McCroskey was made executor of the estate of Eli Hunter. He later married Hunter's widow, Sarah Ann, the daughter of David Bright. McCroskey himself was dead by 1832, for in that year Mrs. McCroskey married William Demetris Lacey.
