Looking at that thread they name Lewis Cass Payseur. Ill have to check into it but Lewis Cass (without the Payseur) is a name well known in the Detroit area. We have a road named after him , Cass Avenue, and a high school, Cass Tech.

From wiki:

Lewis Cass (October 9, 1782 – June 17, 1866) was an American military officer, politician, and statesman. He represented Michigan in the United States Senate and served in the Cabinets of two U.S. Presidents, Andrew Jackson and James Buchanan. He was also the 1848 Democratic presidential nominee.

But the timelines seem off. How can Lewis Cass, born around the same time as the Prince, have established the residency in Michigan to become a Michigan Senator with the Prince in North Carolina and most of his early holdings seeming to be mostly in the South?

Tangled webs. The victors write the history.

Its also interesting to note that the witch Whitmer stripped the Cass name off a State office building because he was a slave owner.
