John Symon and Ann Currie had James Symon illegitimately in Grange, Banffshire in 1800. In 1807 Ann comes down from Grange and they marry in North Leith, Edinburgh. 1809 a son John is born, John's occupation is a Porter at Coal Hill (I googled that). James has an illegitimate son christened in Grange in 1828, with a witness John Symon (father? brother too young?) - so family looks to be back in Grange by then. Ann is a widow in Rothiemay, Banffshire in 1841, 1851 and dies in 1856 with no husband/occupation named, but informant is son, James Symon. In 1877 James died in Rothiemay and the informant (neighbour) says his father is John Symon, Private Soldier.
I have checked NAS and NA and can't see any soldier John Symon, I assumed that it meant a soldier rank Private when I first saw it but after the recent talk of mercenaries... I am not sure if there would be any register of Porters at all? Any suggestions of documents that might mention him? Specifically I am after identifying where/when he was born.
