What is "hostarius"

The Hostarius (alternatively, Usher, Doorward or Durward) was an office in medieval Scotland whose holders, eventually hereditary, had the theoretical responsibility of being warden of the king's door: protecting the king's property. This is a list of hostarii.

• Malcolm de Molle, uncle of Alan fitz Walter, 2nd High Steward of Scotland
• Jocelin, reign of William the Lion
• Thomas de Lundin (son of Máel Coluim son of Gille Críst, Earl of Mar), d. 1231
• Alan Durward (son of Thomas), d. 1275

The family of "Durward" (a later name for hostarius) may have held the office hereditarily after Thomas of Lundie, and certainly kept the title as a surname (in Norman French, l'Ussier ("the Usher"); in English, Durward) The office was no longer hereditary by the second half of the 13th century, and indeed, by then, there were many hostarii. Unlike many other hereditary royal office holders, the "Durward" family were not of Anglo-Norman or French origin but native Gaelic origin. It was a sept of the native comital dynasty of Mar.
