'Boscobel', the Horatio Seymour Shonnard Sr. estate enlarged by Donn Barber c. 1918 in Oyster Bay. The house, which is not pictured, was built for Francis T. Underhill c. 1885 with alterations by George Post c. 1888. Barber changed the house from a Queen Anne to a Colonial Revival as well as adding a garage, stables, boat house and formal gardens. Shonnard was a stockbroker and descendant of Horatio Seymour, governor of NY in the 1850s. The house was demolished in the 1950s but click HERE to see the extant stables and some of the gardens and HERE to see the property on google earth. If I can locate pictures of the main house I will add them.
