I can't speak for Hartmann, but there's a book on Hans Joachim Marseille by Colin Heaton, and he compares all of Marseille's claimed kills with allied loss records, and is able to put a name, unit, and aircraft to Marseille's kills.
There were a few kills he couldn't corroborate, but not many. Discrepancies often stemmed from front-line clerical errors regarding time/date and sometimes misidentification of aircraft.
There were also some kills that were "probable" or claimed as "damaged" but were never confirmed at the time. However, according the the author, he was able to corroborate 11 additional kills for Marseille. So in reality, Marseille got more kills than his official kill count.
The wiki on Marseille is poorly written, I think. Many of the wiki sources are outdated or have been revised since. I've read all of the books on Marseille including Tate's, which is heavily referenced throughout the wiki, and Heaton's is by far the most comprehensive.
Also, for a kill to be confirmed in the North Afrika theater, it had to be verified by multiple sources. Sometimes they used army units on the ground or a Fieseler Storch to spot the claimed enemy wreck on the ground. In Marseille's case, many of the allied pilots were rescued from the desert, by Marseille himself.
Heaton's book does make mention of two German pilots in North Africa who were padding their kills with fake claims by spotting wrecks on the ground and claiming it as their own. The ploy did not last long and the two pilots were demoted and reprimanded.
