English : occupational name for a herdsman who had charge of rams, from an agent derivative of Middle English to(u)pe ‘ram’ (of uncertain origin).German (Tüpper) : occupational name for a potter, from Middle Low German duppe, Rhenish düppen ‘pot’. This is predominantly a Rhineland surname.This is the name of a family descended from two brothers, originally from Kassel, Germany. They fled religious persecution in the 16th century, settling in the Netherlands, where a descendant became burgomaster of Rotterdam in 1813. A branch of the family settled in England at Sandwich, Kent, whence another descendant, Thomas Tupper, went to America in 1635, and helped to found Sandwich, MA, in 1637. Benjamin Tupper, born in Stoughton, MA, in 1738 was a colonial legislator and explorer of OH.

English, Scottish, Irish, German, and Scandinavian : from Middle English hall (Old English heall), Middle High German halle, Old Norse hǫll all meaning ‘hall’ (a spacious residence), hence a topographic name for someone who lived in or near a hall or an occupational name for a servant employed at a hall. In some cases it may be a habitational name from places named with this word, which in some parts of Germany and Austria in the Middle Ages also denoted a salt mine. The English name has been established in Ireland since the Middle Ages, and, according to MacLysaght, has become numerous in Ulster since the 17th century.Hall is one of the commonest and most widely distributed of English surnames, bearing witness to the importance of the hall as a feature of the medieval village.
