Allynwood Academy, formerly the Family Foundation School, was a private, co-educational, college preparatory, therapeutic boarding school located in Hancock, New York. The school was in operation from 1984 through 2014, when it closed due to declining enrollment amid a raft of physical, emotional, and sexual abuse allegations made by alumni in a grassroots "truth campaign." At least ten lawsuits have been brought by former students since 2019, in which plaintiffs claimed that strip searches, hard labor, isolation rooms, physical restraint, and sexual assault were rampant at the school in the 1990s and 2000s. Three of the lawsuits were settled in October 2021 for undisclosed sums. A front-page New York Times article in 2018 reported a pattern of at least one hundred deaths by overdose and suicide among alumni, the vast majority before age 40.

Hancock is a village in Delaware County, New York, United States. The population was 908 at the 2020 census. The village is in the west part of the town of Hancock at the junction of NY Routes 17 and 97. Hancock is located at the confluence of the East and West branches of the Delaware River. Hancock owes its former importance mainly to the Erie Railroad from 1848. The Erie merged into the Erie Lackawanna Railway in 1960. The railroad still exists as the Southern Tier Line of the Norfolk Southern Railway, leased to the Central New York Railroad, but sees only a few freight trains weekly. The Scranton Branch of the New York, Ontario and Western Railway bridged the West Branch of the Delaware River just west of the village; this railway's main activity in the area was at Cadosia junction, a few miles up the East Branch of the Delaware River. Though the O&W ceased operations on March 29, 1957, the bridge was not removed until the 1970s.
