I have looked at a birth record on SP and the parents are given as James Millar and Catherine ms Robertson. Marriage January, 1863, Crieff.
However, I cannot find that marriage on SP so looked on FS and found a marriage between a James Miller and Catherine Robertson 8th January, 1863 Muthill, Perth.
My knowledge of Perth's topography is not good but after googling Crieff and Muthill I gather they are not very far apart and so it may be worth looking at this record. However, I can't find this marriage on SP either!
Any suggestions as to how to find the marriage on SP will be gratefully received
Thank you
