you need to check both Braddan and Douglas St Matthews films as there was a John Kewn + Elizth Moore m Braddan 1786-11-25 (but patron submitted and I've not checked these years yet) - the IGI has children including a william bapt DSM 1797-05-17 to a John Kewn + Ann Moore (no marriage found) with other children to John Kewn + Elizth Moore but all are patron submitted except for a margt as 1st child which has a submitted Mary on same date (this is a classic error in IGI when patron submitted entries were used to replace extracted entries)
