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 O. Meyer
Jacob Owen Meyer (November 11, 1934 – April 9, 2010) was the founder and directing elder of the Assemblies of Yahweh (not to be confused with the pre-existing Assembly of Yahweh) which was the largest organization within the Sacred Name Movement.
Meyer was born in Bethel, Berks County, Pennsylvania. He grew up in a conservative, religious German-descended family, and was active in his local Anabaptist congregation. He studied at the Evangelical Congregational School of Theology (now the Evangelical Seminary) in Myerstown, Pennsylvania. While there, Meyer found himself concerned that professors, teachers and theologians who confirmed that the Biblical name of God was "Yehovah" (of which "Yahweh" is a variant) used terms such as "God" outside the classroom. Believing that liberalism was undermining the Church of the Brethren denomination to which he belonged, Meyer and his wife began to look for alternative religious groups including Sacred Name Movement groups.
