Herbert De Lamare, or, as he was called in Irish, Erebeirt an Muireach, (muireach: Irish, “a sailor or mariner”), was considered to be of French extraction.

He came into Ireland upon the first invasion thereof by the English, and, after a time, was made governor of the lower borders of Meath, now called “Westmeath,” then the limits of the English conquests in that country; where he and his posterity obtained great estates and possessions. This Herbert de Lamare was the ancestor of Delamere, anglicised Delmore; after him the Irish called his descendants MacErebeirt (“erebeirt”: Irish, a load or carriage; from the Gaelic “eraidh,” apparel, and “beirt,” a burden), anglicised MacHerbert and Herbert.

William de Lamare, son of Herbert, lived in the reign of Henry the Third, King of England; and founded the Abbey or Friary of Multifarnham, upon part of his possessions.

John de Lamare (or Delamare), son, it is supposed, of the aforesaid William, built the strong castle of Street, in the territory of Maghbreacry, in the country of Annaly (now the county “Longford”), which he made his chief seat, A.D. 1294; and so continued to the chiefs of his posterity, until their estates were confiscated by Cromwell and his adherents, during the “Commonwealth.” In the same year (of 1294) this John Delamare joined with John Fitzgerald, baron of O’Phaley (now “Offaley”), who was afterwards first earl of Kildare, in a great quarrel between him and Richard Bourke, the Red Earl of Ulster; and, by his assistance, defeated and took the said earl, and committed him prisoner in the Castle of Ley, for a long time. After the year 1298, the said John Delamare was slain in an engagement with his Irish enemies of Annaly.
