DENNIS, THOMAS MASON -- The records of the Texas Veterans Association, of which he was a member, show Mr. Dennis as having been born in Georgia but the year of his birth is not shown. In the Headright Certificate issued to him January 9, 1838 for one-third of a league of land by the Matagorda County Board it is stated that he came to Texas in April, 1835.

Mr. Dennis was issued Bounty Certificate No. 4059 for 320 acres of land for having served in the army from February 28 to June 1, 1836. He was a member of Captain Jesse Billingsley's "Mina Volunteers" at San Jacinto and on July 14, 1838 he was issued Donation Certificate No. 465 for 640 acres of land for having participated in the battle.
