Declaration of Independence (1819) In 1745, Lewis married to Elizabeth Annesley (died 1779), a sister of his business partner, Thomas Annesley. Together, they were the parents of seven children, three of whom survived to adulthood: • Ann Lewis (1748–1802), who married Captain George Robertson (1742–1791) of the
Royal Navy. • Francis Lewis Jr. (1749–1814), who served as churchwarden of St George's Parish in
Flushing, New York, from 1791 to 1794. He married Elizabeth Ludlow (d. 1831), daughter of Gabriel Ludlow, Esq. •
Morgan Lewis (1754–1844), who married
Gertrude Livingston, the daughter of Judge
Robert Livingston of
Clermont. He was a governor and attorney general of New York. In 1775, Lewis acquired and relocated his family to an estate located in
Whitestone, in present-day
Queens. The home was later destroyed after the
Battle of Long Island by British forces, who also arrested his wife Elizabeth. She was eventually released in a
prisoner exchange for the wives of two wealthy Loyalists from
Philadelphia, though the hardships Elizabeth endured in captivity ruined her health and led to her death in 1779. Through his eldest surviving daughter Ann, he was a grandfather to Marianne Robertson (1779–1829), who married
John Bird Sumner, the
Archbishop of Canterbury and brother of
Charles Richard Sumner, bishop of
Winchester. Through his son Morgan, he was a grandfather of
Margret Lewis (1780–1860), who married New York lawyer and politician
Maturin Livingston and became parents to twelve children. ==Death and legacy==
