hi my name is Nancy Thorndyke Reed andmy sister are trying to find out more about our grandfathers history . As you will probably notice the spelling is different so we are not sure if anything is connected. We are thinking that the name was changed somewhere along the way any info. About John or Clarence Thorndyke. John is our gg grandfather and Clarence is our great grandfather. They would be from the upper Michigan area. Dates would be late 18 early 1900's.
