Horace Higgenbotham is a resident of Horner's Corners near Winfield, Kansas. He's also a childhood acquaintance of Mary Ann and possibly a former schoolmate. It's not really known the level of their friendship, but she remembers him mostly as a creep. After Mary Ann was stranded on the island, she pretended that Horace was her old boyfriend and with Gilligan's help, she sent several bottled messages out to him from the lagoon. Horace later went on to marry socialite Sybil Wentworth with condolences to Sybil from Mary Ann.
