I guess you have traced family to Edward son of William Bailie + Catherine Callister in Peel - I'm currently researching Peel Families and have come to a stop at this William (tho I havn't yet looked at the Wills) - I can't find any burial for William tho there is a will dated 1789 which would just fit as he had at least 3 children John, a possible William , Catherine and Edward (from whom your line decends) 1789 and earlier - the 1814 Peel Census shows a John and Edward as heads of 2 households - John's is with one Female - this could well be his mother who did not die until 1827.
However I also have a Alexander Bailie who signed the 1759 petition re Peel harbour and who appears to have died 1765 but no linkage between Alexander and William. (on a side note there are several patron submitted entries for a William bapt 1787 which could fir however I can find John and Catherine in the Confirmation lists for Peel but no William)
I wonder if you have made the link or have any further info you could add - there is I suspect both from name and fact that a Catherine Baile married widower Colin Ross in Peel in 1793
