In typical fashion for Wikipedia, there's a flurry of activity parroting yesterday's headlines, namely this story, in lieu of actually searching out higher-quality sources.  Their entry long referred to him as "Lowell Jackson Thomas, Jr.".  The quote from Anne Donaghy intrigued me, so I went back to Who's Who in Alaskan Politics and sure enough, it says "Lowell Thomas, Jr." without a middle name.

Probably long forgotten is the fact that there's been a long tradition in the state's history of newcomers running for congressional office due to not meeting residency requirements for state office.  Thomas was perhaps the first of these.  I've previously mentioned that he was a party to the controversy surrounding the Ernest Gruening-Ted Stevens Senate race in 1962, but it's probably best not to rehash that episode at this time.
