Kinn-ucher, without the y! But anyone who has trouble with the guttural Scots -ch-, as in (Kilconquhar) loch, can just use its official pronunciation, as per the spelling - Kil-conker, as in the things that fall off trees and that kids play with (except when forbidden by health & safety rules).
By the way, remember that people mentioned in the records as being in Kilconquhar parish might actually be in the villages of Colinsburgh or Earlsferry, rather than in Kilconquhar village itself.
