Donald Ramsay - Data

Where did you find this information about Donald b. 1707, d. 1758, m. Janet M'Kinley, being the father of John Ramsay b. 1728, Ugadale Argyllshire, Scotland d. 1798 m. Margaret Taylor?

I have been researching this for some time but have not been able to find any data on it. I know that John traveled on the Annabella in 1770 to PEI Canada, and I have traced my line down from him through eight generations.

Could you please help?
