Well, my Patrons are St. Philomena and St. Michael…
The Masculine form of Philomena is Philomenos (or Philoumenos).
I don’t know if there’s a St. Philomenos on the Latin calendar, but there are several on the Byzantine Calendar.
The most recent one is a martyr, Hieromonk-martyr Philoumenos, caretaker of the Orthodox chapel at Jacob’s Well in Sychar on the West Bank, who was killed by members of the JDL. Rabbi Meyer Cohene boasted about it.
Of course, you could always adopt Philomenos in honor of St. Philomena.
And there’s also St. Philemon (close enough) for whom one of the Pauline Epistles is named.
