Mark 15:21: Verse 21
A Cyrenian - One of Cyrene, a celebrated city in the Pentapolis of Libya.
The father of Alexander and Rufus - It appears that these two persons were well known among the first disciples of our Lord. It is not unlikely that this is the same Alexander who is mentioned, Act 19:33, and that the other is the Rufus spoken of by St. Paul, Rom 16:13.
