CATON, Richard, merchant, born in England in 1763; died in Baltimore, Maryland, 19 May, 1845. In 1785 he became a merchant in Baltimore, and in 1790 entered into an association for the manufacture of cotton. He was particularly interested in geological researches, and was one of the founders in 1795 of the library company, whose collection was merged in the library of the Maryland historical society. In November, 1786, Mr. Ca-ton, who was a tall, handsome man of fine presence and dignified carriage, married Mary, daughter of Charles Carroll of Carrollton, a social favorite, admired by Washington as her eldest daughter was admired by the "Iron Duke." Of their daughters, Mary became Marchioness of Wellesley; Elizabeth, Lady Stafford; Louisa, Duchess of Leeds; and a fourth, the wife of Mr. John McTavish, British consul at Baltimore, whose son married Ella, youngest daughter of General Winfield Scott. The three sisters, who resided in England, were celebrated for their fascination of manners, and Lady Wellesley for her beauty also. There is in Baltimore a portrait of Lady Wellesley by Sir Thomas Lawrence, which is admirable alike in" execution and likeness. Mrs. Caton's portrait is presented above.
