 The family derives its surname from lands in Wales, likely from the Honour of Montgomery which was located near the Shropshire lands of the FitzAlans.There is no evidence of any familial connection between Clan Montgomery and the family of the Counts de Montgomerie, Earls of Shrewsbury, of Anglo-Norman origin who derived their own surname from lands in Calvados, Normandy.The earliest member of the clan in Scotland was Robert of Montgomery, and the earliest possessions of the clan (in Scotland) was Eaglesham, in Renfrewshire.
