YOu may have already found this out by nowbut I have Wyman Wakefield in my treee who was the son of your Timothy and Chloe Chapin. I show Timothy and Chloe dying in Sackett's Harbor, Jefferson Co, NY a month apart in 1827. Wyman and family lived in Belleville and Ellisburg in Jefferson Co. Wyman died after 1870 as he is in the 1870 census in Ellisburg living with his son,John.
I show the Pardon you mention as being born in 8 Mar 1808 in Jamaica, WIndham Co, VT and dying 28 Mar 1885 but don't have a place.
I also show Timothy and Chloe marrying on 10 Sept 1784 in Wardsboro, WIndham Co, VT I have full birth dates for I think all their chidlren and a great deal on Wyman since he's connected tomy family. Have a few death dates but not all for the children.
