Now that we've met the incomparable Mrs. Elton, I must say a few words about the names JA has given to the characters in "Emma." Some of them show a Shakespearean sense of wordplay, much as Dickens would years later, imho.

BarbataB has previously mentioned that Hawkins, Mrs. E's maiden name, was the name of the man who introduced the slave trade to England, and the book implies that perhaps Mrs. Elton's family came by their money in that way. But even without that connection, the name Hawkins reminds one of a hawk circling its prey, or a merchant "hawking" his wares. Put together with her first name Augusta, it sounds like the noise my cat makes when he's dislodging a hairball!
And her brother-in-law Mr. Suckling! I have to imagine JA found it hard to keep a straight face when she wrote Mrs. Elton's constant mentions of "Mr. Suckling's seat." Mrs. E. also boasts of her acquaintance with a Mrs. Bragge. They sound like a bad reality show, the Real Housewives of Bristol.
There are some other character names that also reflect their bearers' personalities or social standing. Poor Miss Bates seems to be waiting with bated breath to pounce on anyone who comes to visit. Woodhouse and Churchill both denote some kind of property -- to this day, Churchill is of course a famous name. Fairfax = fair facts. And Harriet Smith, a nobody, has a very anonymous sort of name to go with her lack of parentage.
And of course, there's Knightley. Mr. Knightley is a very courtly man, and also a nightly visitor, it seems, to Hartfield. And speaking of "nightly," one doesn't wish to be naughty, but it does seem that John and Isabella have a new baby every year! No wonder her father calls her "poor Isabella."
