Meaning and origin unknown. The element 'peti' occurs in other names (Peti, Petiallam, Petikesari, Ishapeti). It may be of Nubian origin, deriving from ⲡⲉⲧ(ⲧ)ⲓ-, 'date, date palm'. The element 'isha' is otherwise unidentified, however.
This may be a variant of Ishapeti (Nam 201030).
Meaning: 'graced with beauteous garlands'.
Inspiration: the word does not seem to occur in Christian literature, but is well attested in classical Greek works, including Homer and Hesiod, where it functions as an epithet of Artemis or Demeter. No doubt, the parents of the Eustephanos were educated persons versed in Greek literature.
