Rufus is the son of Simon (of Cyrene). His mother played a significant role in the early church.
Mark 15:21A certain man from Cyrene, Simon, the father of Alexander and Rufus, was passing by on his way in from the country, and they forced him to carry the cross.
Romans 16:13Greet Rufus, chosen in the Lord, and his mother, who has been a mother to me too.
