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 R. H. Neervoort van de Poll
Jacob Neervoort, grew up in Velsen with his aunts. In 1880 his stepfather died at the age of 42 and left the Rijksmuseum a collection of 52 paintings. For this gift his son was allowed to carry the name Van de Poll. Neervoort collected paintings, especially from the Barbizon School and the Hague School, travelled to the Dutch Antilles and joined a diplomatic and trade delegation to Japan. In 1887 he married. Till 1894 they lived on Herengracht, on the Golden Bend. Then the couple moved to "Beukenstein" in Driebergen.
Neervoort van de Poll amassed a vast beetle collection, much of it purchased from the Paris insect dealers Auguste Sallé and Émile Deyrolle. It included many expensive beetles, especially (Jewel scarabs). In the Japanese garden he had a sort of a pagode built for his collection. The collection was sold on his death and specimens are now found in many museum collections.
