the choices are:
St John the Evangelist - Cronk-y-Voddy A Chapelry Church built 1852.
St John the Baptist - St John's Present building consecrated 1849.
St Peter - Peel Built as Chapel of Ease to the then Cathedral of St German's on St Patrick's Isle probably around 1550 (though some date it earlier). When the old Cathedral fell in disrepair it became the joint parish church for Kirk Patrick and German.
