had issue William de Windsor or Carew, to whom King John, by deed dated 1212, made a further grant of Molesford, reciting the former deed of King Henry I. to his grandfather. So that this William was the first of this family that assumed the name of Carew. Thus Prince again, the author of the Antiquities of Oxford, is positive that this family of Carew was denominated from Castle Carew, in Pembrokeshire, and not otherwise. Thus God in his providence, to check our presumptious jnquisitions and pretensions, hath wrapped all things in uncertainty, bars us from long antiquity, and bounds our search within the compass of some few ages, scarcely affording any true record of pedigrees or descents as far back as the Norman Conquest, whatsoever to the contrary is by some men and families pretended.
Lastly, as this family was denominated from one of their ancestors being Constable or Castellan of the Castle of Carew, in Pembrokeshire, for carew doth not signify a plough in British, for ardar, aradr, arar, is a plough in Welsh, Cornish, and Armoric, and kaer, caer, is a castle or fortified place. Carew, caer-ew, care-eff, is he, his, or her, Castle, as ipie, ipea, ipeum. See Ffloyd. Caer-eau, British Saxon, is a castle or fortified place of water, referring perhaps to the medical or purgative waters there.
As Mr. Carew saith his family was denominated from one Carrow or Karrow that came into England with William the Conqueror, so I must tell you that there was in Cornwall and Devon, not long since, a genteel family surnamed Carrow (id est, deer) who gave for their armes, as appears from Nich. Upton's Latin manuscript book of Heraldry, before printing was invented, now in my custody, dated 1444, in those words, " Monsieur Joh'is de Carrow, port d'or iii lyons passant sable which is now the arms of those gentlemen before-mentioned, named Carew. Care-w, after the English Cornish, is he, his, or her care, watchfulness, or circumspection.
