Thank you Gavin for more information regarding non Kirk of Scotland marriages, although it has left me even more confused. The couple were both from Old Deer ( groom ) and Fraserburgh ( bride ) and actually married in St Nicholas, Aberdeen and then with or before the Sheriff in King St., Aberdeen. They were both Episcopalian, and the bride's father's family were also from Old Deer, so I don't know why they didn't marry in St Margaret's in Aberdeen or back in Fraserburgh or Old Deer. They both disappear afterwards - I think that they must have emigrated but don't know where to. They don't appear on the 1901 or 1911 Scottish or English / Welsh census. Another puzzle! Mary
