He arrived in Nacogdoches in 1835 with only twenty dollars but ultimately acquired a large farm and began a new life as merchant and farmer. He married Keziah Catherine Harrison, daughter of William Fenley, on December 26, 1850; and on November 24, 1853, he married Ellazina Harris, daughter of Elbridge G. and Mary Hamilton Harris. With his third wife he had three children.
As his financial condition improved, Blake soon began acquiring additional land in Nacogdoches County and over all of East Texas. Some he purchased outright, but much he acquired as a result of his moneylending. For many years, while Texas laws prohibited banks and restricted banking operations, Blake lent varying sums of money to his fellow Texans, the loans usually being secured by land and land titles. In effect, he functioned as a private banker and consequently as a land speculator. He entered upon a distinguished career in public service shortly after his arrival in Texas. His neighbors first elected him a justice of the peace in 1838 and reelected him until, by 1850, he had served some ten years in that office. Thereafter, he became chief justice of Nacogdoches County, an office he held for twelve years. In these twenty-two years he reportedly heard and decided 7,000 civil suits and 500 criminal cases. Blake fought in the Texas Revolution. He also served under Gen. Thomas J. Rusk in an expedition against the Cherokee Indians in 1839 and engaged in a second Cherokee expedition in 1841. East Texas voters elected him to the state legislature in 1862, and he became one of the Texas delegates to the Congress of the Confederate States of America, where he served during 1863–64.
After the Reconstruction period, voters again chose him to represent them at the Constitutional Convention of 1875, where at age sixty-six he was the second oldest delegate. Thereafter, although his friends and neighbors urged him to continue in service to the public, he declined to accept public office and concentrated instead on his banking and farming. Judge Blake was a Democrat and Mason. He died in Nacogdoches County on March 1, 1896, and is buried in Oak Grove Cemetery in Nacogdoches.
