Hello Peter,
Look at Steve Brew's site at http://brew.clients.ch
Choose "Databases", then "Databases for the Isle of Man", then "Brew of Ballavarran, Jurby.
Patrick was a younger son of Patrick who died 1704 [under No.1].
You will see a lot of other information about the Brews of Jurby in his other databases as well.
Best wishes,
Sue
