"HOWEVER, your ancestors also INTENTIONALLY gave smallpox ridden blankets to Native people, women and children included. So, please do not re-write history and sugar coat it."

No, my ancestors never did any such thing.  Please do not insult them like that.

The worse thing that any of them did was that my Great-Great Grandfather shot and killed 3 Indian braves while traveling on the Oregon Trail in 1853.

No one else in my family tree has ever done anything else to harm Native Americans, either before or since that incident.  And he had no choice that day 163 years ago.   He had to kill them.
