Tschudi (variants: Schudy, Shudi, Schudi, Tschudy) is a surname common in the Canton of Glarus, Switzerland.
The Tschudi name can be traced back to 870. After Glarus joined the Swiss Confederation, and in 1352 various members of the family held high political offices at home, and were distinguished abroad as royalty soldiers and in other ways.
Several branches of the Tschudi family and their servants' families, who took on their masters' last name, first began immigrating to the United States in the mid-18th century (1700's), where the name Tschudi had its spelling changed to Judah, Judy, and Judey. All are in usage still.
