Yes, I know where she is buried--I've sent you an email, but if it doesn't get through, you can contact me.
Jerusha died June 11, 1803 and is buried at Northhampton Massachusetts.
Her gravestone inscription reads:
"Mrs. Jerusha Lyman, wife of General William Lyman d. 11 June 1803 in the 43rd year of her age."
I am trying to get more information on their daughter, eldest of five who opened a boarding school in Philadelphia shortly after her father, General William Lyman died in England.I can be reached at firstname.lastname@example.org
