Theophanes names "Bardas nuper Armeniacorum dux, Constantinus vicarii spatharius et excubitorum domesticus, Theophylactus Rangabe filius et Duodecim insularum drungarius" as conspirators against Emperor Leon IV in favour of his half-brother Nikeforos (in 780) and records their exile...
Patrikios. The Anastasii Historia Ecclesiastica ex Theophane records that "Michael magistratus, Lachanodraco et Bardas patricius ac Stephanus protospatharius…" among those killed in battle "XII Kal Aug", in the second year of the reign of Emperor Konstantinos VI (792), at "castrum Marcellorum" in Thrace against the Bulgars...
Genesius names "Leo…imperator, Bardæ quidam patricii filius, sed genus ducens ex Armenia". It is not certain that these three references are to the same person but it looks likely. In particular, it appears probable that only one individual of the name Bardas would have held the dignity of patrikios at any one time.
The name of Bardas’s wife is not known. Theophanes Continuatus records that "Leonem…eius mater oblata" supposedly had a vision in which the Patriarch threatened her son if he continued attacking icons and pleaded with him to change his policy. Theophanus Continuatus records that, after her son was murdered, Leon’s mother was sent to the monastery of the Despotai with Leon’s widow. 1
--------------------------------
As Settipani convincingly argues, Leo's father Bardas married the sister of Bardanes the Turk. This marriage seems to have cemented an alliance between the two families and fostered the career of Leo, who began his military training under Bardanes' command.... 2
