When my mother was about my age she attendent Acadia University, Wolfville, King's County, Nova Scotia, Canada. She loved doing genealogy in her spear time, just like me, so most of the information I have is from her research at Acadia. All the dates are correct but you are missing three children of William Blenkhorn, Jr (s/o William Blenkhorne and Christina Sief) and Olivia Ann _______. And they are John Amos Blenkhorn b:1770, Ann b:1772, and Eleanor b:1773. William, Jr. came across the Atlantic Ocean on the ship "Two Friends" along with his Wife Ann 29, William 7, John 4, Ann 2, and Eleanor 1 - he was 33. Left England March 7, 1774 and arrived in Halifax, Nova Scotia May 9, 1774 from Hull, Yorkshire, England. They left England because, I qoute, "On account of their rents being raised". Six children were born before their voyage but two died before. As for the Clark family goes, I have a Susan Clark m: Thomas Blenkhorn on January 3, 1864. He was the s/o David Blenkhorn and Dorcas Mills. And for your last question, most of the Blenkhorn's orginiated from Cumberland County, Nova Scotia; around the Maccan area. I hope this helps you on your journey and if you ever need anything else, just e-mail me.
