He was a son of the distinguished general Leo Argyros, and had at least one brother, Marianos Argyros, who also occupied high military posts.
The sources disagree on when the marriage took place: the 11th-century historian Yahya of Antioch asserts that the marriage took place before Lekapenos' rise to power, while the late 10th-century chronicler Theophanes Continuatus records that it took place in 921.
In either case, the marriage represented an effort by Lekapenos, a provincial upstart, to solidify his position by linking his family to one of the most prestigious aristocratic families of the Empire.
[2][3] As such, Romanos became the brother-in-law of Constantine VII Porphyrogennetos, who had married another of Lekapenos' daughters, Helena Lekapene.
[4] His great-grandson was Emperor Romanos III Argyros (r. 1028–34), who became emperor by marrying Empress Zoe, the great-granddaughter of Constantine VII.
