Dear Tony, just looked at your posting. I'm not sure if we have a connection, but I have both Garretts and Quirks in my family tree and my Garretts originated in Lezayre.

I have John Garrett b. abt 1739, Lezayre, who married Joney Curghey. I have traced 5 children including Ewan Garrett b. 1767, Lezayre, who married Catherine Christian. They had 11 children including Elizabeth Garrett b. abt 1797, Andreas. She married John Mylrea. They had 12 children including Catherine, born 1821 Andreas. She married John Quirk in 1843. John Quirk is may g-g-grandfather.
