John Blair, Alamo defender, was born in Tennessee in 1803. On February 19, 1835, he registered as a married man for a league of land in Texas. He may have been one of the volunteers who accompanied James Bowie to Bexar and the Alamo in early 1836. Louis Rose, who left the Alamo before the final battle, later testified that he "Left [John Blair] in the Alamo 3 March 1836." Blair died in the battle of the Alamo on March 6, 1836.
