Thank you for putting that together! And I see you found the Henry T as I did who's father is William A.. That is where the trouble is for me because William A. is connected to William G. and the line goes back to John/Elinor Whitney of Watertown Mass (1635). That is what is on the Whitney Research Group page anyway. But my DNA test results from Family Tree DNA (Whitney project)shows that is not possible.
That being said, Henry T would not be my grandfather's grandfather. I do know from my grandfather that his grandparents are Henry and Alice. But from there back I can't find a record of Henry E's parents.
Again, thanks for putting that together!
