Grosvenor, from gros venor, 'fat hunter'.

That's excellent. I'm intrigued by Beaglehole, Clutterbuck, Cronk, Dingus, Eggink, Footlick, Gimbel, Hipkiss, Hollobone, Limp, Midgette, Mincey, Muddle, Nettleship, Noblin, Ogletree, Owl, Pardon, Pickles, Puffinburger, Riddles, Smelley, Spankie, Splatt, Thicknesse, Toadvine, Tremblay, Tubby, Twaddle, Twitt, Underdown, Whatmuff, Windy, Winker, and Wrong, but they probably mostly have mundane and logical origins. The ancestral Pickles probably just pickled things a lot, for instance.

Unsurprisingly the family behind this Norman French aristocratic name owns most of west London. The Duke of Westminster is one Hugh Grosvenor.

"Autocorrect" as in "ducking autocorrect won't let me curse"?

Something like that I guess.
