as your query started out and had an entry put on the Co Down board, Aghadowey mentioned Ros Davies Co Down board, one of my favourites. I looked again today at Ros davies and was struck that she had no McGauchie at all, and sounded out to myself the name and found myself looking at her McGaughey and Megaughey entries in Comber civil parish and Knockbreda civil parish and a little wider nevertheless a couple of pocket areas. One of her earliest listings is William MEGAUGHEY . Comber of Magherascouse; aged 26, attended Magherascouse School in 1824 MSch p6. I produced a historical directory of Comber some years ago, its about 30 mgs in size downloadable from Comber historical Society website, but my work is already dated and Ros gives more uptodate information. You might find my information on Magherascouse useful perhaps. You should try contacting the Comber historical Society itself. Good luck onwards JimG
