I am trying to find more information on Robert Waterson who died in 1775 on IOM and lived near Ballapodag, Braddan. His wife was Mary Cowin

Children were:
Thomas Waterson
Margaret Waterson
Esther Waterson
John Waterson

I believe he is my ancestor and I'm looking for more information to confirm this such as the year of birth of his children, mainly his son Thomas
