Sylvanus Castleman

Sylvanus Castleman is one of Stephen F. Austin's Old Three Hundred settlers who received one of the first land grants in the colony of Texas. His land was the first of the 297 grants from Austin, which he received on July 7, 1824,

Castleman arrived in Texas from Missouri in 1821. His land grant was located near La Grange, TX along the Colorado river.

His exact date is not known, though it is believed that he committed suicide. Researchers know that he died prior to March 10, 1832, as his wife Elizabeth Castleman posted notice in the Telegraph and Texas Register on July 8, 1840, that his estate would be presented before probate. In 1841 she was granted 800 acres of his land from his estate.
