Sorry. The family history I have is that Sir George Pippie, from Scotland, escaped from France at the time of the French Revolution and the Guillotine. The Hume Castle that they occupied was too high for water to be used in the moat so it was filled with thistle bushes to deter any enemies. The name Thistle was applied to the family after a while. Supposedly a Hume Thistle left Scotland and sailed to New Brunswick, Canada and became a Whaler. He had seven sons and they all built Whaling boats and became Captains of them. A Christine McCoy Thistle was born in Hume Castle but she ran away as a young girl and was disowned by her parents. George William Ozard Thistle, born March 06, 1832 in Newfoundland married Mary Rebecca Hume, daughter of George Hume and Christina McCoy. I find the prior story an incredible play on words or names as it were and have not been able to verify any of it. Have you or any one else heard this story before? Let me know if you would. Herb.
