From: Robert G. Ferris (editor), Signers of the Constitution: Historic Places Commemorating the Signing of the Constitution, published by the United States Department of the Interior, National Park Service: Washington, D.C. (revised edition 1976), pages 200-201:
Paterson, one of the authors of the New Jersey, or Paterson, Plan, was one of seven foreign-born signers [of the U.S. Constitution]. Although he made his career primarily as a lawyer-jurist and reached the pinnacle of his success as Associate Justice of the U.S. Supreme Court, his political offices included attorney general, legislator, and Governor of New Jersey; and, briefly, U.S. Senator.
William Paterson (Patterson) was born in County Antrim, Ireland, in 1745. When he was almost 2 years of age, his family emigrated to America...
In September 1806, his health failing, the 60-year-old Paterson embarked on a journey to Ballston Spa, N.Y., for a cure but died en route at Albany in the home of his daughter, who had married Stephen Van Rensselaer. Paterson was at first lad to rest in the nearby Van Rensselaer manor house family vault, but later his body was apparently moved to the Albany Rural Cemetery, Menands, N.Y.
