The second eldest living relative of Elizabeth MacKay and John Law (first son of my GGF Thomas) confirmed that Thomas (GGF) was a deserter and remained in Scotland, when home on leave, to marry Janet Myles who was pregnant. This line of the family firmly believe that this was when the name change to 'Knox' occurred. It is a valuable clue and gives a possible time-point for desertion prior to the wedding of Thomas and Janet in August 1892.
