Hall was born in Dublin on 6 January 1800. She lived with her mother, a widow named Sarah Elizabeth Fielding, and stepfather, George Carr of Graigie, Wexford, until 1815. The daughter came to England with her mother in 1815. Anna Maria was educated in part by Frances Arabella Rowden, who was not only a poet, but, according to Mary Mitford, "had a knack of making poetesses of her pupils" This ties Anna Maria to other of Rowden's pupils such as Rosina Doyle Wheeler, later Rosina Bulwer Lytton; Caroline Posonby, later Lady Caroline Lamb; the poet Letitia Elizabeth Landon ("L.E.L."); and Emma Roberts, the travel writer.
