I would like to confirm Alex's remarks with a paragraph from the Menologion of Saint Dimtri of Rostov:
"The holy Simon was a native of Cana of Galilee and was known personally to the Lord and to His all-pure Mother, for the town of Cana was not far distant from Nazareth. When Simon celebrated the occasion of his marriage, he invited to that festivity the Lord, His immaculate Mother, and His disciples. Since there was a shortage of wine for the guests, the Lord changed water into wine [cf. Jn 2:1-11]. Struck by this miracle, the bridegroom came to believe in the Lord Jesus Christ as the true God, and, leaving his wedding festivities and his very house, he followed after the Lord with zeal. Hence he received the name �Zelotes,� or �the Zealot,� since he was enflamed with so great a zeal that he forsook his own bride for love of Christ, wedding his soul to the Heavenly Bridegroom. For this, Simon was numbered among the assembly of Christ�s disciples and in the ranks of the twelve holy apostles."
