There doesn't appear to be a lot of evidence one way or another, but should Vsevolod Glebovich of Iziaslavl be named as Wetseke's father instead of Borys Davydovich? Or paternity left unknown due to lack of evidence? The connection to Visvaldis also seems to be muddled as both presumed fathers have been variably assigned to both. Possible cousins instead of brothers? Not connected at all?
