No problem daffe. Your information is not wrong. I put a link to the profile we have here on MD, which I think is the most historically accurate (not the most popular). Anyway, it is good to compare information sources and find the most logical common thread. The Bandog is derived from the Mastiff breeds but is not really an English Mastiff. Could have been a mixed English Mastiff at some point in time.... I have to see what my copy of the book says. All the best.
