[2][3] The house was purchased from Charles Halderman as a private residence in 2009 by Bo Young and William J. Foote and is not normally open to the public.

The house is not architecturally distinguished, but does retain some period features, including wide floor boards and a large kitchen fireplace with a pot crane and a beehive oven.

Born to a white woman and man of African descent, Haynes spent his early years in indentured servitude, but was educated by his master and introduced to the Congregational church.

He served in the local (Granville, Massachusetts) militia during the American Revolutionary War, after his indenture ended, and was formally ordained as a Congregationalist minister in 1780.

His service as minister to the Middle Granville church marks the first known instance of an African-American preacher leading a predominantly white congregation.
