[4] In the much later years of his life, especially after the death of Nathan E. Cook, who had long been hailed as not only the last surviving veteran of the Spanish–American War but of any American engagement, debate raged over the trustworthiness of Jones Morgan's claim to have served.

Several experts, including military archivist Mike Knapp and Commander Carlton Philpot, USN, say no concrete evidence can be brought forth of Morgan's time in the army, but that they did not doubt him.

Morgan met former president George H. W. Bush and then-Chairman of the Joint Chiefs of Staff, General Colin Powell, and led the Veterans of Foreign Wars parade.

He was interred at the Forest Lawn Cemetery in Richmond, Virginia with a commemorative plaque atop his tombstone denoting Morgan as a Buffalo Soldier.

The Ancestry.com website shows there is a 1942 World War II Draft Registration card listing Jones J. Morgan, a resident of Richmond, Virginia, born on October 23, 1888, in Newberry County, South Carolina.
