Locárd
LOCÁRD—VIII—Locard, Loccard, Lokard, Lockard, Lockart, etc.; 'son of Locard' (a French personal name, from Teutonic Lochard). This surname came into Ireland about the time of the Anglo-Norman invasion. About the year 1200, Jordan Loccard was witness to a grant by Philip de Nugent to Holy Trinity Church, Dublin. There is a Ballylockard, or Lockardstown, in Co. Westmeath which was probably the first home of the family in Ireland.
