“cean-dromaidh and cean-drumaidh (John Michie says he has heard both” Diack MS2276

“[kɪlˈdrʌme, kɪlˈdrɪme, kɪlˈdrɔməɪ]. Pronounced Kildrummy; sometimes nearly Kildrimmy or Kildromie…. (Gael, cean-dromaidh and cean- drumaidh—D.) The old spellings together with the Gaelic form show that the name is ceann druim(in), end of the ridge. It illustrates the facility with which Scot, speech may turn Kin- into Kil-. Kildrummie in Nairn has similar old forms.” Alexander, 308

Thanks to Simon Taylor for the early forms.
