You are the first person to inquire about Hezekiah's children. As to Milton C. Goodgion, I have very little on him - only information of his Military Service. Here is some of what I have.
Milton entered the Confederate Army at Camp Boone, Tennessee -- 150 miles from his home in Hickman County, Kentucky. He served for 3 years or for the period of the war. He began as a Private on July 5, 1861, was promoted to Corporal on September 20, 1863, then, 2nd Corporal, and, finally, was made 4th Sergeant between March 1st and April 1st, 1864. He was killed in battle, August 31, 1864, in Atlanta, Georgia.
