I never read Lawrence, but I was intrigued and frequently delighted reading about Gerald's far-flung childhood habitats and the creatures he encountered/adopted/studied.
If I have a literary hero, it's probably Robin Hood. I have a collection including children's and YA novels (Wyeth and Hildebrandt illos!), romances, fantasies, and scholarly examinations of the myth and legend including an 1850's book with leather spine and quarterboards entitled Robin Hood: Being a collection of Ballads and tales from the Borderlands...and I forget the rest. It goes on quite a ways. It's a very odd little thing, but I'm pleased to have it. Second (heh. of course) would be F'nor of the Dragonweyrs, second in command to his more flamboyant brother F'lar, figurehead and leader of the weyrs. F'nor was rider of brown Canth, in McCaffrey's first two Pern novels, loyal, perceptive, observant, and reflective, more levelheaded than his brother, and a half-step out of the limelight. My kind of guy.
Girl heroes: Nancy Drew, Podkayne of Mars, Menolly of the Harperhall, Marion in McKinley's Outlaws of Sherwood, Gillan in Norton's Year of the Unicorn, lots of Norton's women and girls, who seemed to function just fine with or without male support, Harriet Vane.
I'm sure there are more of either gender, these are all that come immediately to mind.
