Individual Details

She could be the Annie Eastman who married Asa Dustin I think as his third wife. But there is also another 1793 Anna Eastman.
I think it could be this one and will put her in there.

There is a Sarah Thrasher age 87 living with Asa and Anna in 1850 --this could be either Asa's mother or Anna's mother. I think it is Asa's mother since she died in 1858.

The Dustin Association books, I think, give the birth date of Asa's third wife as the same as this Anna.
