Aubaine

• abstract: In old French customs, aubaine (, windfall) was the inheritance of goods from a foreigner who died in a country where he was not naturalized. The word is formed from aubain, a foreigner, which Gilles Ménage derived further from the Latin alibi natus; Jacques Cujas derived from advena; and du Cange from albanus, a Scot or Irishman, by the reason that these were anciently frequent travelers living abroad.
