The marriage in Holy Island: 31 May 1807 William Tait of the parish of Shillbottle and Isabel Wilson of this parish by banns Wit: Robert Tait, William Brown and Thomas Wilson.
My guess why the records are in Shillbottle is because banns were also called there. The LDS did not always say those were banns and recorded as marriages which just confuses all.
I don't know if this is your family or not but there is a baptism in Holy Island of Jane Tait 2nd daughter born 22 Sep 1811 baptised 27 Oct 1811 d/O William Tait, labourer native of Norham, by his wife Isabella Wilson, d/o Thomas Wilson, Fisherman of Holy Island.
