Who is the girl snogging teddy lupin in Harry Potter and Deathly Hallows?

There's no mention of Teddy Lupin snogging anyone in Harry Potter and the Deathly Hallows.

While Teddy is a teenager by that point, the books don't focus on his romantic life. He does, however, develop a crush on a girl named Victoire Weasley, the daughter of Bill and Fleur Weasley, in later books.
