At the same time, the different Killerby’s all appear in the Domesday Book as Culuerbi or Chilurobi expressing the weakness of Norman ministers to recognize and convert the solid local accents of that period perfectly. The explanation of the hamlet name can be 'The infant’s agreement' associated before the 7th century from the Ancient English and Norse word "Cilda-bi." It did not mean a baby or children but was a particular name of affection provided either to a first infant, or more similar as lands and partnerships combined, to the firstborn infant of a regional administrator.
