Killingworth Family History

From North and South Kilworth (Leics), which often has medial -ing- in medieval spellings (such as Killingworth about 1291 in Taxatio Ecclesiastica), or from Killingworth (Northumb), which is recorded as Killingworth in 125. The Leics place-name probably derives from an Old English personal name *Cyfel + the Old English place-name forming suffix -ing or the group-name suffix -ingas (genitive -inga-) + Old English worð ‘enclosure.

The Northumb place-name probably derives from an Old English personal name *Cylla + Old English connective -ing- + worð.
