Béla III of Hungary
Smaragd ("Smaragdus") or Zsámbéki was the name of a "gens" (Latin for "clan"; "nemzetség" in Hungarian) in the Kingdom of Hungary. The ancestor of the clan was a French knight calling himself at that time "Ainordi (Aynard) de Champagne", who settled down in Hungary around 1186 during the reign of Béla III of Hungary and received use of the estate of Zsámbék under a royal grant. His descendants, the "gens" Smaragd built the Zsámbék Premontre monastery church.
