Historical Forms

  • Chilvertebi, Chiluertesbi 1086 DB
  • Kilverdebi, Kilverdeby 1155–65 Whitby 1231 Ass
  • Kiluerdby 13 BylE
  • Kilvardeby 1247 Ch
  • Kelwardeby 13 Percy

The first element is without doubt identical with the pers. name Chiluert which is found in DB. It enters into Kilverstone (Nf), and a lost Kuluertestuna , Culuerdestuna (DB) in Colneis Hundred (Sf), one of the forms of Marishes 84supra , Killerby 245infra , Killerwick (PN La 205), and a lost Killerby in Lei (IPN 86). Björkman (NP 81, ZEN 54, Loanwords 25) supposes that it is a hybrid pers. name of which the themes are ON  Ketill (frequently reduced in Scand  dithematic names to Kil -) and the common OE  theme -weard . The persistence of -verd forms, however, may occasion some doubt as to the correctness of Björkman's suggestion, and one may suggest that the name is from an OE  compound name Cēolfriþ , Cēolferð , composed of the very common themes Cēol - and –friþ , or an ON  name *Ketilferð composed of the themes Ketill - and –ferð .Later forms however show confusion with OE  -weard . v. by .
