FOSTER, ISAAC (?–?). Isaac Foster, one of Stephen F. Austin's Old Three Hundred colonists, was probably the son of John Foster and the brother of Randolph Foster. He came from Mississippi to Texas in 1822. As one of the Old Three Hundred he received title to one sitio of land in what is now Matagorda County on August 10, 1824. On February 1, 1830, he was ordered to appear before the ayuntamiento at San Felipe de Austin to testify concerning the improvements on his land. On March 1, 1830, the ayuntamiento reported that Foster had cultivated the land and lived in the country since the land was granted to him but had recently died in the colony, leaving many relatives. Though one Isaac Foster's will was probated in March 1839, in 1859 another Isaac Foster or his estate was given a bounty warrant for 320 acres of land for military service from March to June 1836.
