Louisa Hasbrouck, the third daughter of Levi and Hylah Hasbrouck, was born on August 20, 1831. Like the rest of her siblings, Louisa’s early education started with tutors at home. Later, she probably attended the Poughkeepsie Female Collegiate Institute (founded in 1848). Louisa never married. She lived her entire life at Locust Lawn. Louisa Hasbrouck died in Poughkeepsie, N.Y. on November 21, 1867 while staying with her sister Ann Bevier Hasbrouck Innis. As stated in a Family Record death both kept by Hylah, Louisa was "36 years 3 months + 1 day after a lingering illness of consumption."
“Death does not often call from us one who had stronger and sweeter ties to bind her to earth. Her position was not merely enviable because every earthly comfort that this world’s goods can confer was hers, but she was singularly blessed with a flow of priceless love which most deeply mourns that its dear object has been removed."
