Now having that name, I would note that it certainly does align with those nationalities, and that the convention of script signature of either maker or supplier of blade in late 18th c. was at this location typically on blade back.
The forces I mentioned, were indeed of pandour type in French armies as well as certain other European armies, and their forces were often of Balkan and East European nationality, many Hungarian.
This style of oriental/exotic motif on the blade was well known in these times in Nantes in France as 'Caissagnard', and often had a 'Turks head' or a turbaned figure.
