Melchior Steudl (painter/draughtsman; 1680; fl c)
17th Century painter from Bavaria.
The surmane Steudl (mostly found in Bavaria) comes from Steidl more commonly used in Germany which comes from Steydl an earlier Germanic surname used by Danes (Vikings) around 600 A.D.
History suggests that the Steudl family migrated or "viking'd" from Denmark to Bavaria in the 7th century.
Melchior Steudl is the earliest Steudl I could find and he has works located in the British Museum.
