He was married to a distant cousin of his named Sarah Hines Bennett, daughter of Benjamin Bennett and Susanna Lucinda Taylor, about 1833 in Smith Co., TN

Harrison was the son of William Bennett and Jane Vannatta. Harrison Bennett was also one of my gr, gr, great grandfathers.

In all Harrison and his wife had eleven children, all of whom grew to adulthood and married.

Harrison served during the War with Mexico and reached the rank of 3rd Corporal during that war (1846-1848).

Later, when what is now referred to as the Civil War broke out, he re-enlisted and served as a Captain in Company H of the 9th Regiment of the 4th Brigade of the Missouri Infantry. He resigned, due to ill health, in 1863, and subsequently moved from his home in Missouri to Randolph County, Arkansas, to take advantage of the beneficial hot springs in that area. He lived only about four years after resigning from the military and died in 1867, at the relatively young age of 53.

The following is from Murial Bennett Minium's 1983 book "Bennett - A Listing of the known descendants of John M. Bennett as of July, 1983"

Researcher Laymon (Kenneth Laymon) sent the military record of Harrison Bennett. A Captain, he resigned because of ill health from Company H 9th Regiment, 4th Brigade, Missouri Infantry (Confederate), in 1863. His letter of resignation came from a camp near Little Rock (Arkansas). He quite honestly stated on his resignation that he believed he would be better off in the country than in hospitals. Had rheumatism. This was 8 years after the birth of Henry Sterling (Bennett), and he would have been 49 years of age. So he only lived 4 years after that. It is logical that he moved to RaC (Randolph County, Arkansas) to take advantage of the health beneficial waters at Warm Springs, Arkansas.

He and his family moved from SmC (Smith County, Tennessee) to StF (St. Francois County, Missouri) at the same time as his father, William Bennett. Remained in StF (St. Francois County, Missouri) until c (circa) 1854 at which time he started southward, being in Iron Co., Missouri, for a short time before arriving in RiC (Ripley County, Missouri) about 1859. Continued southward and arrived RaC (Randolph County, Arkansas) c (circa) 1863, where he remained until his death. Both he and his wife believed to be buried in the old Thompson Cem. which is in the vicinity of the old Bennett homestead. Farmer. Methodist.
