The following surname origins were taken from the Dictionary of American Family Names, Oxford University Press, ISBN 0-19-508137-4:
STADLER German: from a derivative of Middle High German stadel ‘barn’, ‘granary’, hence a topographic name for someone who lived near a barn or granary, or occupational name for an official who was responsible for receiving tithes into the manorial storehouse. The surname is also occasionally borne by Ashkenazic Jews, apparently as an adoption of the German surname. It is also found in Slovenia, where it is commonly spelled Štadler.
STATLER Variant of German Stadler.
