4. BAUDOUIN of Antioch (-killed in battle Myriokephalon 17 Sep 1176). One manuscript of the Lignages d'Outremer records that "la princesse Constance" had two (unnamed) sons and two (unnamed) daughters by her first husband[178]. Niketas Choniates names "uxoris suæ [referring to Emperor Manuel I] sororem…cum Balduino fratre" when recording that they left Antioch for Constantinople[179]. After his mother was sent into exile in 1163, Emperor Manuel I invited Baudouin to Constantinople where he joined the imperial army[180]. He was killed during Emperor Manuel's final push against the Turks in Asia Minor by Kilij Arslan Sultan of Ikonium/Konya[181]. Niketas Choniates records the participation of "Balduinus imperatoris sororius" in the battle and his being killed[182].
