His paternal grandparents were John Lawrence and Deborah (née Woodhull) Lawrence and his maternal grandparents were Capt. Joseph Sackett and Elizabeth (née Betts) Sackett. His family was large and many members were prominent in New York business and politics. His brother Daniel Lawrence was an Assemblyman and his nephew Nathaniel Lawrence (son of Thomas) was New York State Attorney General. Congressman James Lent and Recorder Richard Riker were his great-nephews.[1]
Career
At a young age, Lawrence became a merchant, visiting Europe and the West Indies in the employment of his eldest brother, John Lawrence before joining the house of Watson, Murray & Lawrence. After inheriting his brother John's estate and a portion of his brother Nathaniel's estate (who died unmarried in the West Indies), he retired c. 1771, around age thirty-four, and purchased a residence at Hurlgate which had been owned by his great-grandfather Thomas Lawrence, the youngest of three brothers who emigrated to America around 1645.[1]
Beginning in May 1775 Lawrence was a member of the 1st, 3rd (May to June 1776) and 4th New York Provincial Congresses (beginning in July 1776, which became known as the First Constitutional Convention).[1]
Revolutionary War
In 1772, he had been appointed captain in the provincial militia by the royal government.[1] Once the New York Provincial Congress organized a militia in 1775, he was appointed major of the Queens and Suffolk brigade under Gen. Nathaniel Woodhull.[1]
In August 1776, on the eve of the Battle of Long Island, his militia was sent to drive livestock in an effort to prevent it from falling into British hands. While the activities indirectly claimed the life of Woodhull, he had been ordered to Harlem to seek reinforcements from General George Washington.[1]
On March 16, 1766, he married Judith Fish (1749–1767), the daughter of Nathaniel Fish and Jannetje (née Berrien) Fish (a sister of Judge John Berrien). Jannetje's niece, Elizabeth Berrien, was married to Fish's nephew Nathaniel Lawrence, and was the aunt of John M. Berrien, the United States Attorney General under President Andrew Jackson. Before Judith's death on September 29, 1767, at age seventeen, they were the parents of one son:[1]
Jonathan Lawrence (1767–1850), a merchant with Lawrence & Whitney who married Elizabeth Rogers.[4]
After his first wife's death in 1767, he married Ruth Riker (1746–1818), a member of the Riker family, for whom Rikers Island is named. Ruth was the daughter of Andrew and Jane Riker. Together, they were the parents of nine children, including:[1]
Judith Lawrence (1769–1827), who married John Ireland (1749–1836).[1]
Margaret Lawrence (1771–1851), who died unmarried, aged 81.[1]
Andrew Lawrence (1775–1806), a sailor who died "of the African fever, in one of the Dutchfactory islands, near an outlet of that river, which has since been discovered to be the ancient Niger."[1]
Richard M. Lawrence (1778–1856), a merchant who sailed around the world, and upon his return to New York in 1815, became the vice-president of the National Insurance Company and then president of the Union Insurance Company, both in New York.[1]
