Harry married Ginevra "Ginny" Weasley, somewhere between 1998 and 2005. They had three children: James Sirius (named for Harry's father and godfather), Albus Severus "Al" (named after two headmasters of Hogwarts) and Lily Luna (named after Harry's mother, and Harry and Ginny's "dear friend" Luna Lovegood). I hope that helped.
