Wezelin, advocatus monasterii sancti Michaelis in monte in civitate Polensi (1065, 1068), nobilis miles (1079)

St. Michael’s monastery, represented by abbot Iuvencius and advocate Wezelin, exchanges properties with a Berthold.

A Johnny Vilico bestows to St. Michael's monastery and its abbot Iuvencius his property in Rumijan under the condition that his son Martin enjoys the usufruct of this land for four years.

Pope Gregory VII admonishes a noble knight Wezelin for attacking Dalmatia, ruled by a ruler approved by the Holy See, and orders him to immediately stop with the hostilities lest the "sword of St. Peter" be unleashed upon him and his followers.
