Annette Innis Young was the daughter of William Hopkins Young and Martha Innis Young. The granddaughter of George Innis and Ann Bevier Hasbrouck. She was born in Poughkeepsie, and educated at home by private tutors. She enjoyed playing golf with her father, riding horses on the Locust Grove estate, and enthusiastically recorded her family's activities in her diary. A member of a wealthy and socially prominent family, Annette generously gave time and money to a wide variety of charitable and philanthropic organizations that focused on preserving natural and historical resources. Her love of animals was reflected in her active support of the ASPCA. In 1963, she oversaw Locust Grove's designation as a National Historic Landmark, at that time an unusual step for a privately held property. Annette spent 80 of her 90 years living at Locust Grove, and clearly recognized the estate's national importance as the home of Samuel F. B. Morse. Annette also inherited Locust Lawn (The Josiah Hasbrouck House) from her brother Innis (1887-1953). Annette Innis Young (1885-1975) in turn bequeathed the property to the Huguenot Historical Society (Historic Huguenot Street), in 1958.
