it's part of Bishops Barony - as I said the activities (courts, sales etc) are in a sep book which has never been filmed - Wm Cubbon first librarian at Manx Museum had it as one of his favourite items and used some examples from it - I photoed several years whilst doing some work In Patrick (a fair amount of Barony lands there - look at Woods Atlas on CD) but on reviewing these pages see no entry of Jurby (maybe I was selective in my photoing - can't tell as pages are not numbered) - there may be some in Lib Canc(Chancery Court) as I have noted some sales there and one referred to Rendoo which is Barony (see appx H in 1926 Manorial Roll transcription )
