Which Uncle Was at Buchenwald?

Many people have stayed on the case with regard to Barack Obama's claim of having one of the uncles on his American side present during the liberation of one of the infamous camps set up by Nazi Germany. When it was recalled that the senator's mother was an only child, reasonable observers figured out that he had to be talking about a brother of either of his maternal grandparents. As it turns out he has only two great-uncles old enough to have served in WWII,* one on each side--Ralph E. Dunham Jr. and Charles Payne, brothers of his grandfather and grandmother, respectively.

As for which camp was liberated, it turned out that the uncle in question, Mr. Payne, had been a part of the 89th Infantry Division which took down Ohrdruf--a part of Buchenwald--rather than Auschwitz, the death camp which had been originally cited by Obama. So after the details were straightened out, everyone was happy.

Except for the fact that the details are not straightened out.

Dan Riehl:

His only Great Uncle is Charles W. Payne [sic]. It at least appears that no one by that name from Kansas served in the Army during WWII.

Charles W. Payne of Kansas, with a similar birth era, served in the Navy during WWII.

However, the folks at Sweetness and Light went to the 89 Infantry Division Site to reconcile the information. And after some BDS-infused charm displayed by the site's proprietor, got the information requested: whether a Charles W. Payne served in the 89th Infantry Division which liberated the Ohrdruf concentration camp. Answer:

Concerning the service of Mr. Charles Payne: C.T. Payne was a soldier in the 89th Infantry Division. He served in the 355th Infantry Regiment, Company K. The 355th Infantry Regiment was the unit to liberate Ohrdruf. Mr. Payne was there.

Charles T. Payne did serve in the unit in question on the mission in question.

Which brings up two more questions: 1) Is this same Charles Payne an uncle of Obama's, and 2) What about Mr. Dunham?

UPDATE: According to Tully, Ralph E. Dunham Junior's name does not appear on the roster of the 89th Infantry Division site.

*Obama also has another great uncle but that one is in his seventies--too young. (Thanks to notropis)
