Bar-Jonah in the Bible Encyclopedia - ISBE
bar-jo'-na (Bar-ionas): Simon Peter's patronymic (Mt 16:17).
Bar is Aramaic for "son" (compare Bar-timaeus, Bartholomew,
etc.), and corresponds to Hebrew ben. Thus we are to
understand that Peter's father's name was Jonah. But in Jn
1:42; 21:15-17, according to the best reading, his name is
given as John (so the Revised Version (British and American),
instead of the King James Version Jona, Jonas). There are two
hypotheses to account for this difference: (1) Ionas (Jonah)
in Mt 16:17 may be simply a contraction of Ioanes (John); (2)
Peter's father may have been known by two names, Jonah and
Barjona Scripture - Matthew 16:17
And Jesus answered and said unto him, Blessed art thou, Simon
Barjona: for flesh and blood hath not revealed [it] unto thee,
but my Father which is in heaven.
