Sorry to jump in on this thread but I am also looking for information about the Sagers from either Richmond County or Addington and Lennox Counties. I believe that my ancestors moved around between the two counties. I also strongly suspect that they are Loyalist descendants.
Specifically, my inquiry is about the parents of my 3x great-grandmother Dorothy Sager (1824-1887). Dorothy was born in Richmond County and later lived in both Napanee, ON and also Tyendinaga, ON with her husband Elias Julius Johnson/Johnston (1820-?).
I’ve attached a screenshot showing where Dorothy Sager lived and died as well as the dates in case that will help.
