"Danville's Bacon Century Farm Surrounded by Lore of Indians" -
In Harvey's Hollow here, high on a hilltop where the view spreads across the hills and valleys to distant towns, stands the homestead of Mr. and Mrs. Beverly Bacon. The property to which the Bacon's reside, was purchased on January 28, 1800 by Beverly Bacon's ancestor Eliakum Hunt, from Nathaniel Chamberlain of Newbury, Vermont. The land which was deeded is situated on land lot 56 just east of Keiser Pond in once what was known as Deweysburgh, Dewey's Gore, or "the Boot". It was annexed between Peacham and Danville in 1810.

Mary Ann, daughter of Eliakum Hunt and Sally (Russell), married to David C. Bacon, and in 1853 received the farm's deed from her father. It continued through the family in 1894 to their son John A. Bacon and to John's wife Minnie and their son Beverly J. Bacon in 1929. Beverly and his wife, Mildred, are present day owners (1967)

In 1800, during the time that the present Bacon house was built, a tribe of peaceful Indians (Abenakis) inhabited the hilltop. At first, they were reluctant to move, so they stayed in their wigwams on land now the family's front lawn. After awhile they retreated to nearby Keiser Pond, but occasionally came to the hilltop and sat with their backs against the buildings. Those Indians appeared friendly and would often borrow a small brass kettle and other cooking pans from Mary Ann, Beverly Bacon's Great Grandmother. Upon returning them they were polished brightly and in the kettle was always a fresh caught fish or chose piece of venison."
