Jacob Westervelt (sheriff)
Jacob Westervelt (1794–1881) is often confused with his brother-in-law John Jacob V.B. Westervelt (1805–1866), who was a Deputy Sheriff under him, and subsequently High Sheriff of New York City himself too (1846–1849), as well as Assistant Alderman from the 16th Ward (1844–1846). Another namesake is Jacob Aaron Westervelt (1800–1879), the shipbuilder, Alderman from the 13th Ward and later Mayor of New York City (1853–1855).
Jacob Groenewegen
Jacob Groenewegen (died 22 May 1609) was a Dutch merchant, who was the leading merchant ("opperkoopman") on the fleet under Pieter Willemsz. Verhoeff that left Texel on December 21, 1607, and arrived in Bantam on February 15, 1609. Like Verhoeff, he died on May 22, 1609 on one of the Banda Islands, in an ambush set up by the islanders.
