Almoner

n. one who distributes alms, one who gives donations or aid to the needy; social worker in a hospital

Almoner (from the Greek ελεημοσύνη, westernized as eleemosyna, 'alms' via Latin Almosunartius and French, known in English since circa 1300) is a chaplain or church officer who originally was in charge of distributing charity. Historically, almoners were Christian religious functionaries whose duty was to distribute alms to the poor. Monasteries were required to spend one tenth of their income in charity to the poor (a tithe).  Bishops kept their own almoners and almoners were attached to the courts to the Kings of France.  Charles VIII of France had a Grand Almoner in his employ.
