View source for Casier, Joost (d. after 1656)

Joost Casier (or Cesaer) was a deacon of the [[Waterlanders|Waterlander]] Mennonite congregation at [[Leiden (Zuid-Holland, Netherlands)|Leiden]], [[Netherlands|Holland]], at least until 1656. In a letter of 1614 he signed his name with the French addition, <em>diaque des Valon a Leiden. </em>The letter, also signed in French by [[Mortier, Jean de (17th century)|Jean de Mortier]] as <em>Evesque </em>(bishop) and Jean des Mullier as <em>Serviteur </em>(preacher), seems to indicate the existence of a separate congregation called <em>Vallons, </em>that is, French-speaking Mennonites, originally from the Walloon district of [[Belgium|Belgium.]]
