Just had a very quick look at Public Members Trees on Ancestry

There is one tree with a John KILTIE who married a Mary BLAIR - 23 November 1869, Kirkmaiden, Wigtownshire -

Even if you try 'Googling' sometimes you get a 'hit' with someones family tree.

Rootsweb Sct - Wigtownshire - seems to have a few KILTIE message on their archives.
