Sophia[1] Croft (née Wentworth) is a character in Persuasion. She is the sister of Edward and Captain Wentworth. She is married to Admiral Croft of the Royal Navy.
Mrs. Croft and her husband are well off. When Sir Walter Elliot puts Kellynch Hall up for people to rent, she and her husband take it while Sir Walter and his eldest daughter are in Bath. Her brother, Captain Wentworth comes to stay with them at Kellynch[2]. He was rich and had come in order to find a wife. He harbored none of his regard for Anne Elliot, even though he loved her once[1]. When her brother started pursuing the Musgrove girls, namely Louisa, Sophia didn't make a fuss but secretly didn't think either of the girls were good enough for her beloved brother.
