Angus McMunn is first listed on Manorial Roll c.1764 - see transcriptions at http://www.ee.surrey.ac.uk/Contrib/manx/towns/peel/1764_mr.htm - probably arriving c.1759 as the 1750 book notes that a deed change passed thro court in May 1760 - I havnt chased that note but it ties in with Goodwin's comments re him coming over at that time (he may have come over earlier and merely rented a proptery)
