It's long standing fan theory that Kakashi's mother is from the Inuzuka clan, but I've never agreed with it, but I do agree her elemental talent would have to be water. Also, because his father was known as the White Fang, it's likely Kakashi's contract with the nin-ken was from him, not from the Inuzuka clan.
