John Dinsmoor was born in Ireland in 1721 to Robert and Margaret Orr Dinsmoor, and came to Windham with his parents and three siblings in 1730. John later married Martha McKeen of Londonderry and the their family grew to include thirteen children. Dinsmoor is recorded as having been one of the leading men of the town, serving as town clerk, a moderator at town meetings, selectman, justice of the peace, elder at the Presbyterian church, and a delegate to the Provincial Congress at Exeter in 1775. He died in Windham in 1793. However, as evidenced by the late 1795 bill above, it was approximately two years before a, "large and Elegant Double Grave - stone" was purchased for his grave by his son, John. The bill for two pounds eight shillings also included a provision for the second, "two Dollar" blank gravestone to be filled at a later date, possibly when John's wife, Martha passed away.
