Watt of Broadsea

I am trying to find out about my dad's family. His Granda was George Watt (b 1865), fisherman, 40 Broadsea, married Margaret Fairburn Dougal on 29/01/1890. His mother was Christian Crawford (1843-1902) who was not married and his father was John Watt, who I am trying to find out about. I believe he was also a fisherman.

Christian's parents were John Crawford (b1806) and Catherine Noble who were married on 21/01/1864 in Broadsea.

I would be grateful for any additional information about my ancestors.
