Sister of Emma Peachy and Elizabeth Charter (1782–1860), the friend and correspondent of George Crabbe (1754–1832; DNB). The three sisters were the daughters of Thomas Charter (1741–1810), a solicitor and estate manager, and Elizabeth Malet (1748–1804), of Bishops Lydeard, Somerset, a family known to Southey’s Aunt Mary, who lived nearby in Taunton. Southey first met Louisa Charter in Keswick in 1804. Louisa and Elizabeth Charter stayed at William Peachy’s house on Derwent Island in 1823 and then travelled south to London with Robert Southey and his daughter, Edith May Southey, of whom they saw a great deal in London as Edith May was often in the company of Lady Susanna Malet, née Wales (1779–1868), widow of Sir Charles Malet, 1st Baronet (1752–1815; DNB), maternal uncle of the Charter sisters.
