Burke (v.)youdaoicibaDictYouDict[Burke 词源字典]
family name (first recorded 1066), from Anglo-Norman pronunciation of Old English burgh. Not common in England itself, but it took root in Ireland, where William de Burgo went in 1171 with Henry II and later became Earl of Ulster. As shorthand for a royalty reference book, it represents "A General and Heraldic Dictionary of the Peerage and Baronetage of the United Kingdom," first issued 1826, compiled by John Burke (1787-1848). As a verb meaning "murder by smothering," it is abstracted from William Burk, executed in Edinburgh 1829 for murdering several persons to sell their bodies for dissection.[Burke etymology, Burke origin, 英语词源]
