With regard to Cold Harbour (supposed "Coluber," which is by no means
satisfactory), it may be worth observing that Cold is a common prefix: thus
there is Cold Ashton, Cold Coats, Cold or Little Higham, Cold Norton, Cold
Overton, Cold Waltham, Cold St. Aldwins, --coats, --meere, --well,
--stream, and several _cole_, &c. Cold peak is a hill near Kendall. The
latter suggests to me a _Query_ to genealogists. Was the old baronial name
of Peche, Pecche, of Norman origin as in the Battle Roll? From the fact of
the Peak of Derby having been Pech-e _antè_ 1200, I think this surname must
have been local, though it soon became soft, as appears from the rebus of
the Lullingstone family, a peach with the letter é on it. I do not think
that _k_ is formed to similar words in Domesday record.
Caldecote, a name of several places, may require explanation.
