By that time the Coulters of Covington County, Mississippi consisted of Peter Coulter's two oldest sons, Jesse and John. They both grew into large landowners, and Cotton Planters. John was the largest Planter of the family in South Mississippi, an influence still evident today. Jesse Coulter did not survive the War. He was killed in his hometown of Williamsburg, Mississippi by Confederate Soldiers.
Accounts say it was an argument that precipitated the shooting.
It is believed that since he did not own slaves the incident could have been the result of his unwillingness to be conscripted into the Confederate Army. This is however only conjecture. Morrison John Scott Coulter answered the pull of the westward movement and joined the settlement of West Texas. He made his home near Gonzales in 1855, and became a rancher on a modest scale. He was also known for his skill as a saddler.
