"Alice" and "Agnes" were used interchangeably for centuries (and sometimes interchanged with "Anne" as well), leading to considerable confusion as to just who was whom.

Ancestry of Alice/Agnes is from G. E. Cokayne, The Complete Peerage of England, Scotland, Ireland, Great Britain & the United Kingdom, Extant & Extinct or Dormant, 2nd edition revised & enlarged by The Hon. Vicary Gibbs and others, Published in 1910, London, The St. Catherine Press.
