Frances Manwaring Caulkins (April 26, 1795 – 1869) was an American historian and genealogist, the author of histories of New London, Connecticut and Norwich, Connecticut.
Through her father, she was descendant of Hugh Caulkins, who came with Richard Blinman,the first minister of the Plymouth colony.
On her mother's side, her ancestry was noted in early English history, Sir Ranulphus de Manwaring being justice of Chester, in 1189–99; another, Sir William, was killed in the streets of Chester, defending Charles I on October 9, 1644.
Her father died before she was born, and her uncle, Christopher Manwaring, was exceedingly fond of his talented niece, aiding her with his library, and for seven years, she dwelt with him.
When she desired to teach, he set apart a room, still called her schoolroom.
She was the first woman elected to be a member of the oldest historical society in the United States, the Massachusetts Historical Society, in 1849.
Her histories of New London and Norwich aggregated the prominent features and details of the lives of the earliest inhabitants.
Her private papers show that she was sometimes affected by depression, and especially felt that she had accomplished very little.
