This article lists the names of all four:
Under the headline "The Last of the Rebel Army," and the subhead, "Four Rebel Soldiers Surrender – They Have Just Found Out the War is Over," the Index detailed a report that four Confederate soldiers had just turned themselves in to Federal authorities on Aug. 14, 1866, nearly 1-1/2 years after Robert E. Lee surrendered the Army of Northern Virginia to Ulysses S. Grant at Appomattox and nearly 15 months after the last Confederate army had capitulated.
According to the report, Anthony Monkas, Thomas Wells and James Brinberter, all of Co. E, 52nd Georgia Infantry Regiment, and Allan Tewksbury of the 43rd Louisiana Infantry Regiment, all members of the Army of Northern Virginia, surrendered after holding out along the Appomattox River since the first half of 1865.
The post goes on to say this:
A search of the National Archives shows no listing for any of the four men, nor any names that are similar in the 52nd Georgia. Further, Tewksbury's purported regiment, the 43rd Louisiana, never existed. Louisiana infantry regiments during the Civil War topped out with the 31st Louisiana.

A closer look at the records available on Fold 3 confirms that no men of the 52nd GA had such names (or similar) and that the only Tewksbury listed as a Confederate soldier was a Captain Timothy Tewsbury listed only as having served in a "Livingston Regt"
