Heh... Scott W, who used to have a show on History Channel, spent an episode purporting to search for a trace of Henry Sinclair's slightly precolumbian castle in eastern Canada, on some coast or island not all that far from Oak Island. That was one of his shark-jumpers.
Well I didn’t know until I researched dad’s side of the family that one of Sinclair’s descendants is related to Columbus by marriage. It’s been a while but it may have been that Columbus married one of Sinclairs granddaughters or g-grandaughters. It was fairly in close line to Sinclair. Some think that may have been where Columbus got the idea to head this way....I’d have to go look it up again to be precise...
...it’s fun to think about anyway...
