My Great G. G. Grandfather had a son John born in 1838 at Lumphanan & in 1871 had a 6.5 acre farm at Burnside.
Also My GG grandfather, Andrew too, son on GGG grandfather who was Andrew, had a son John born in Coull on 31/5/1869. I have not established descendants of this John.
Have you gone back that far . An uncle of mine thought my G grandfather had a brother who went to the states . I am not sure of you place state III ?
Is there a connection to your John ? I am in Australia.
