Maybe someone(M-4) can look in Der Neue Stockel but it would appear he had a sohn named name Jean Missillieur Vienne that signed Baptiste - Missillieur Vienne or J.B. Missillieur Vienne that was active circa 1830 - 1850 but I don't believe it was him. Johann Missillieur may have moved to Praze & left it in his son's capable hands?

Johann Baptist Missillieur was born in Lyon, France in 1781. By 1821 he is recorded as a Master working in Vienna and by 1834 he was in Prague. He died in 1835.

I guess either one could have used Baptist Missillieur. Possibly Johann Baptist Missillieur & Jean Baptist Missillieur???

Kind Regards,
