Named after the Hudson River city of Kingston and Governor Enos T. Throop.
Throop Avenue honours Enos Thompson Throop (1784–1874), governor of New York from 1829 to 1832. Kingston Avenue is one of seven avenues, from Kingston to Buffalo, named after upstate New York cities; NY1 reports they were named in 1835 as a tribute to the Erie Canal. A 1928 Brooklyn newspaper recalled that Kingston Avenue was once one of two Hudson Avenues.
