Иоанн II Комнин
Roger married an unknown lady of the Dalassenos family, which was closely tied to the imperial Komnenos dynasty. He had at least one confirmed son, the "Caesar" John Rogerios Dalassenos. Another member of the family, the "sebastos" Constantine Rogerios, was a contemporary of John Rogerios and served under Emperor John II Komnenos (r. 1118–1143), but his precise relation to Roger is unknown.
