The Windham Historical Society is disbanding its Parson Smith House Committee, which attempted to raise $700,000 to purchase the town’s oldest historically-intact building.

“We’re getting away from the historical slant and replacing it with the agricultural aspect,” said Linda Hanscom, who was head of the committee, which was only able to raise $57,000 toward the purchase of the home.

A group headed by Windham town councilor and equestrian 4-H leader Donna Chapman has shown interest in purchasing the property, according to Don and Elaine Dickinson, who own the 243-year-old house.

Chapman declined to comment, saying details will be revealed at the Sept. 18 town council meeting.

“It hasn’t been a chore to sell the house,” said Elaine Dickinson, 67. “It’s been an adventure.”

Don Dickinson, 77, said he’s heard talk of using the home for agricultural education.

“It’s an entirely different vision for the project,” he said.

The Dickinson’s allow the historical society to tour their home, and agreed to take it off the market last year while money was raised for the purchase. While few details of a possible new arrangement are available, Hanscom revealed in June that new plans for the property included raising crops on the 124 acres of land that comes with the historic house.
