much easier when given info !
suggest William Mclyrea (Mylrea) (not mcybrea a typical igi misread) m jane Kneal als tear m 6 July 1727 - the igi has similarly dated entries for Ballaugh + Kirk Micheal (quite typical for widows) - however can't find a burial but there are a couple of possible burials/wills for wm that should be checked
Margt would appear to be twin - if so then this would certainly be noted in the parish reg which should be looked at for any clues as to residence etc (usually twins do not survive long after birth).
