A.T. Robertson Commentary Romans 16:11

"Salute Herodion my kinsman. Salute them of the [household] of Narcissus, that are in the Lord." — Romans 16:11 (ASV)

Herodion (Hερωιδιωνα). Probably one belonging to the Herod family like that above.

Kinsman (συγγενη). Merely fellow-countryman.

Them of the household of Narcissus (τους εκ των Ναρκισσου). "Narcissiani." There was a famous freedman of this name who was put to death by Agrippa. Perhaps members of his household.
