Hi Debbie, I am a Kaye born ion the West Riding of Yorkshire and confirm that the name is pronounced the same as the letter "K". However, the word key is also pronounced exactly the same in Calderdale. It is therefore possible for Kaye to be miss-spelled Key or even for the name to change. My attavus Benjamin started life being registered as a Kaye and died being burried a Kaye. His fist four children were christened Kay and the next five Kaye. Having recently had shown by Y-line DNA that seven of we Kays,Kayes and Keys are from the same forebear and that our Y-line DNA indicates that we are of Norwegian Viking descent it is possible that the name comes from that part of the world. See Norwegian Kai=a quay or landing stage; Kaie=a jackdaw. Alternatively,the association with Key may indicate a Warder or Watchman or possibly someone who is left=handed.
