^This Secundus is likely the same individual as the Secundus mentioned in the Seven Apostolic Men; see also May 15.[5]
^He is unknown in the Synaxaria. However his memory is recorded in Patmos Codex 256 as follows: "On this day, the contest of the Holy Martyr Ploutodoros"; ((in Greek): «τῇ αὕτῃ ἡμέρᾳ, ἄθλησις τοῦ Ἁγίου μάρτυρος Πλουτοδώρου»).
^This is likely the same saint as the one commemorated on March 31; however a minority of Menologia place his memory here on December 28. In Parisian Codex 1623 f.1436 are found remnants of his Akolouthia. From this evidence it becomes clear that he was ascetic, although it is unknown when and where. S. Efstratiadis speculates that it is not at all unlikely, that this St Stephen is one and the same person as the Venerable Stephen of Mar Sabbas monastery, the Wonderworker, whose memory is celebrated on October 28.
^"ST. ROMULUS and ST. CONINDRUS were probably the first preachers of the Gospel in the island, and flourished while St. Patrick was exercising his apostolate in Ireland. St. Patrick himself is venerated as one of the chief Patrons of Man, and may have visited it some time during his life; but it does not seem reconcilable with his Acts to say, as some have done, that he was its first evangelist."[16]
^Born in Lower Pannonia, he served God as a hermit in several places north of the Alps until he found rest for the last two years of his life as a monk at Lérins in France.
