If Mobi was the original format, would you have converted from Mobi to ePub using Calibre? if so, look at the ePub OPF and if Calibre is no mentioned, then it is the source. That doesn't mean all the ones that do mention Calibre might not be the source, but you can be fairly sure that if Calibre is not mentioned, then that ePub would be the source.

What I do is I have a library for my original eBooks. I do not modify them there. When I want to read something in that library, I copy over to my working library. This way, I always know what the original is and the date added to Calibre.
