[Sir Walter Elliot] . . . married, . . . Elizabeth, daughter of James Stevenson, Esq. of South Park, in the county of Gloucester, by which lady (who died 1800) he has issue Elizabeth, born June 1, 1785. . .
The quote for June 1st mentions the birth on that day of Elizabeth, Miss Elliot, and names her maternal grandfather, James Stevenson, Esq. Where else in Austen's work does the surname "Stevenson" occur?
