Barb,
I have no proof as yet but this is what I have from the IGI
My main family names are KNEALE/CORRIN/ARMSTRONG.
So I looked for my CORRIN names and found: ? my 4th Great Grandfather who was, William CORRIN he married Christian KERMOD(E) 13th Aug 1780 at Malew.

Christian KERMOD(E) was christened on 13th Feb 1757 at Malew.
Her parents were:
John KERMOD(E) and Margaret KAIGHAN who married on 25th May 1754 at Malew.
John KERMOD(E) above was Christened on the 8th July 1729 at Malew.
Margaret KAIGHAN was born on 7th April 1723 to ? Henry KAIGHAN and Jony COSTEAN (Nowadays spelt COSTAIN ).
Henry KAIGHAN was born abt 1686 in Kirk German.
Jony COSTEAN born abt 1690 in Kirk German.
As I say, I have no proof of this as yet, but I hope this helps you in any way.
Regards,
Carol.
