Sir Hugh de Paduinan (1140 – 1189) was a Scoto-Norman baron, Knight Templar and progenitor of the Clan Houston. Both Sir Hugh's given name and surname are subject to a number of different spellings: Hugh or Hugo and Paduinan, Padinan and Padvinan.
Sir Hugh was granted lands in the historic county of Renfrewshire and gave his name to the village of Houston, deriving from 'Hugh's town'.
Sir Hugh was born in 1140 in Great Britain of Norman (potentially Anglo-Norman) ancestry. He is believed to have married a Scottish chieftain's daughter, and his heir was his son Reginald. He was a follower of Sir Walter Fitzalan. Both Sir Hugh and his descendants often arise as signatories of deeds, particularly pertaining to Scottish churches.
He died in 1189 in the Holy Land, possibly amongst the Templars who were killed at the Battle of Hattin.
Sir Hugh is occasionally confused with Hugues de Payens (otherwise spelled Payan, Peanz, Payns or Pedano), a similarly named Knight Templar associated with the churches of Scotland.
