KILLICK
As described in historical dictionaries
Patronymica Britannica (1860)
KILLICK. Perhaps Kihiwick, co. York. Many provincial dialects drop the final N of Kiln; and the w in the termination '-wick ' and '-wich ' is usually suppressed, as in War(w)ick, Nor(w)ich. The northeastern border of East Sussex has long been a great habitat of the name.
