He was 84. I met him once back when I was at A&M and he spoke at the Texas Independence Day event in Washington on the Brazos.
For the record, he is a direct male descendant, but not direct first born line. Sam Houston's son, who fought at Shiloh, was Sam Houston Jr. I don't believe he had any male sons. Sam Houston's last son, Temple Houston, was 3 when old Sam died. He took up the name when he named his son Sam Houston III. That Sam then named his oldest son Sam Houston IV.
