"Callendar House" was built on a bluff overlooking the river in 1794 by Henry Gilbert Livingston (1758–1817), whose country seat was next door. He was the great-grandson of
Robert Livingston the Elder through his grandfather Gilbert. In 1795 he sold it to his cousin Philip Henry Livingston (1769–1831), great-grandson of Gilbert's older brother
Philip Livingston (1686–1749), the second
Lord of Livingston Manor. Philip and his wife called it "Sunning Hill" and occupied it until 1828, when it was purchased by
Robert L. Tillotson. In 1835, Tillotson sold the property to architect Richard T. Auchmuty. William E. Toler acquired the premises in 1854; and then Jacob R. LeRoy, son of Herman Leroy, who founded Le Roy, Bayard & Co. Jacob's sister,
Caroline LeRoy married
Daniel Webster. Jacob LeRoy gave "Sunning Hill" to his daughter Charlotte, the wife of Rev. Henry De Koven. De Koven had served at St. Paul's Episcopal Church in Tivoli; he founded and was first rector of Christ Church in Red Hook. In 1860 it became the property of Johnston Livingston, and then that of his son-in-law, Geraldwyn Redmond. Livingston was on the boards of both Wells Fargo and American Express. "Callendar House" is the name of a former
Livingston mansion in Fallkirk, Scotland. It was one of the names
Robert Livingston had considered for the Lower Manor, but family members objected that it was a prerogative of the head of the family, and so he chose
Clermont instead. It later came into the possession of Jean de Castella, who raised thoroughbred race horses there. Castella renamed it "Tivoli". The property included thirty-five acres. The house has a Federal-style core. A hall bisects the downstairs from front to back. In 1828 one-story wings were added, and around 1830, a veranda. In 1910, a living room was added to the first floor by
McKim Mead & White, as well as a south wing. The murals were painted in 1921 by
Olin Dows. ==References==
