"Dirk III (also called Dirik or Theodoric) was Count of Holland from 993 to 27 May 1039, until 1005 under regency of his mother. It is thought that Dirk III went on pilgrimage to the Holy Land around 1030, hence his nickname of Hierosolymita ('the Jerusalemite' in Latin)." - (en.wikipedia.org 10.04.2021)
