But Lady Russell did not desire to keep Anne more to herself, she wished Anne to marry some man of "talents and independence" worthy of her -- chap 4 --

"she began now to have the anxiety which borders on hopelessness for Anne's being tempted, by some man of talents and independence, to enter a state for which she held her to be peculiarly fitted by her warm affections and domestic habits."

When Anne was 22, Lady Russell wished she had accepted Carles Musgrove -- "Charles Musgrove was the eldest son of a man whose landed property and general importance were second in that country only to Sir Walter's, and of good character and appearance", but when Anne was 19, Lady Russell would have wished for someone superior to Charles Musgrove -- "Lady Russell might have asked yet for something more, while Anne was nineteen".

Lady Russell would not have been favourable to Charles either if he had propsoed to Anne when she was 19 --
"Anne Elliot, with all her claims of birth, beauty, and mind, to throw herself away at nineteen ... Anne Elliot, so young; known to so few", but Lady R became facourable to him when Anne was 22.
