Like many in attendance at the Adolphustown event, Brock Dittrick can trace his family tree back to one of the first Loyalists to settle in Canada in 1784, Jacob Dittrick, who landed near St. Catharines.Both of these quotes may be accurate. He may have been the first to land at Adolphustown, and "one of the first" overall. However, throughout the rest of the article the modifier is dropped and it is implied he was the first Loyalist to settle in Canada.
More than 300 people took part in a re-enactment of the first landing of the Loyalists at Adolphustown following the American Revolution.
Michael Showers was reported to have settled in Niagara on May 30, 1781. And "A survey of the Settlement at Niagara, 25th Aug. 1782" listed Michael Showers, McGregor Van Every, and both of their families (2 wives and 6 kids) for a total of 10 settlers.
I don't know if Michael Showers and McGregor Van Every were the first, but those dates predate 1784. I am descended from both of them through their children Sarah Showers and David Van Every -
