While Wikipedia represents a subsequent marriage to Burchard I, the basis of that information is not considered trustworthy. In particular, DataAnalyst notes, "only one source gives this marriage (www.genealogie-mittelalter.de) and it is not clear if it is reliable - the info is no longer on the web".
