The distinguished surname Senn is an occupational name. It is derived from the Middle High German word "Senn," meaning "farmhand" or "milker of cows." The name was likely first borne by a farmhand, then passed down to his descendants as a surname.
The surname Senn was first found in Northern Switzerland, where the name Senn emerged in mediaeval times as one of the notable families of the canto of Aargau. From the 13th century the surname was identified with the great social and economic evolution which made this territory a landmark contributor to the development of the nation.
