An additional thought:I found a great deal of information on Macphersons from Puslinch in Presbyterian Church records. The two Presbyterian churches in that area were Knox Presbyterian in Crieff and Duff's Presbyterian in Morriston. Their birth, marriage and death records are excellent and available through LDS libraries. These records have been invaluable to me. In addition, Knox Presbyterian in Crieff has published a history of the church which contains histories of the families and some photos.
