An interesting start - but if you are going to take Caroline to Scotland I hope you have been there yourself or at least know something of the country and manners here And just one hint - the term Ms was not coined until the late 20th Century, by the women's liberation movement who objected to Miss and Mrs because they made a woman's marital status immediately evident whereas Mr was the same for all men, At the time of P&P in a family with two or more daughters the eldest unmarried one was Miss Surname and the younger one or ones Miss First Name(s). So Caroline, as a younger sister, would be addressed as "Miss Caroline" until Louisa's marriage when she became "Miss Bingley". Which incidentally means she is not being rude or patronising when she calls Elizabeth Bennet "Miss Eliza" - it's the correct form, and as Sir William Lucas uses it too and Charlotte uses "Eliza" it seems to be how Elizabeth was known outside her family, who use "Lizzy".
