HI Dianne I was also wondering about this 1828 date. It was probably either a fire, a catastrophic accident with a wagon and horses *going over a cliff or into a river?) lightning or war. I doubt if it was disease as they wouldn't necessarily died the same day.The fact that it was a parent with some children leads me to believe it could have been a fire although I have tried to look up an account of an event on that day in that area but haven't found anything yet.
I have been assembling theWellwoods for some years nowbut mostly those in Canada although I do have some scattered throughout the USA. I would be interested in any material on the USA Wellwoods that you have. There is also a large group in Australia/New Zealand as well.
