"Jon Snow," played by Kit Harington, is the son of "Lyanna Stark" and "Rhaegar Targaryen." Since his early years, he was shown as the bastard son of "Eddard Stark," brother of "Lyanna." But his actual family is kept secret from us throughout the show. To distance himself from his given social status, he joins the "Night's Watch."Kit Harington himself is relatively new to acting, with his first documented role being in Game Of Thrones in 2011. He has since then starred in a few different movies including How To Train Your Dragon 2.
