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).
Pieter Hendrik van Zuylen van Nijevelt
He left Luxembourg in 1824 for Utrecht, where he lived in a house on Plompetorengracht canal. There he died in 1825, at the age of only 42 — a year before the death of his father.
