Fiore his master and his students

One of the rare Masters giving a named reference to his masters is Fiore dei Liberi who learned his art in the late 14th century. He claimed to have learned his art from a Swabian (Johanni Svevio) or a Swedish (Iohannes Suenonis - Johannes Westgothi) Master. Later on in his prefaces Fiore is telling us, that he himself has taught Germans and Italians the art of fighting. That sounds pretty much pan-European and a lot of travelling, but is that really the case? A few of the names he wrote down as his students and opponents can been cross identified.
