Hi Barry,
My grandmother was a Rideout from King’s Point, NL. Her father was Giles Rideout from Tilt Cove. His father was Joseph Rideout from Rogues Harbour. Sounds interesting! A post on genealogy.com indicates that Joseph immigrated to Newfoundland from Dorset. He was born to Joseph Rideout (Holnest, Dorset) and Elizabeth Bartelott (Winterborne, Stickland, Dorset, England) who were married on Jan 26, 1775 in Holnest, Dorset, England.
It would be great to touch base with any British relatives!
Cheers
Greg Mitchell.
