The first part "Mc" and/or "Mac" is a Scottish prefix that means "son of”, for instance, McDonald means son of Donald.
Ewen is a Scottish version of the Welsh forms Evan (and leuan according to the New Amen can Dictionary of Baby Names]. In Irish, Evan means "young warrior", in English Evan is a form of John In case you think this is contradictory consider that John the apostle as a young man was one of the sons called "Boanerges which is The sons of thunder." Mark 3:17, obviously John, as a young man, was quite a warrior.
Though Strong’s Concordance has Yehocanan for John, this is not the oldest form. The oldest form of John is Yahuchanan. This oldest form is what the angel Gabriel sought to restore when delivering the name to Zechariah, no human delivered It! The angel bypassed all human corruptions and restored the element “Yahu” in the Baptists name. Zechariah could not speak until after he had written it out. Now this element "Yahu" which is the first part of the sacred name as seen in the King James Version (in two names Elijahu I Kings 17:1 margin, and Obadiahu I Kings 18:3 margin) has gone through several corruptions through the years. Later with the Jewish corruption of Yahu it turned into Yeho. Yahu was shortened to Yu and Yeho was shortened to Yo. Names began to show the change, Yehochanan became Yochanan. In English we have John, but in Spanish Juan. The Karen of Burma call the Creator Yuwa, the Cherokee call Him Yawa. Another example of how "Yahu" was reduced to “lu” is seen in the name Judah, in Hebrew it is Yahudah, then transferring into Greek, it became Iouda and in Latin as Iuda. Also the prophet Jehu (originally Yahu) in the Greek Septuagint is Iou, the English text beside it has “Ju”.
Consider also the name Matthew in the Hebrew is #4993 Mattithyahu, I suspect the same with Bartholomew, which must have been Bar-Tholemyahu (we have big hints of this from Matthew 10:3 in the “DuTillet” Hebrew Matthew translated by James Trimm of the Society for the Advancement of Nazarene Judaism). Also the word Jew is corrupted from Yahu. My point is that the "ew" on the end of these names is a corruption of “Yahu”. 'Thus in the name Ewen or Ewan, pronounced Yooen and Yooan, a form compared to Juan, and also Ivan the Russian form of John, which must have been in it's earlier stages Iuan. Ivan is near the Welsh form Evan. The "E" has switched places with the "I" in Yeshayahu [Isaiah] which in Greek became Esaias. Matt. 3:3 KJV) Immanuel (Isaiah 7:14) becomes Emmanuel in the NT. Ea was the Babylonian corruption of Yah
So a lot of these Ju's, lu's,
Iv's, Yv's, Eu's, Ev's and Ew's are all corruptions of Yahu.
John gives a different timing for the Passover than Matthew, Mark, Luke did! Matthew, Mark and Luke stated YAHUSHUA observed the Passover with His disciples at the Last Supper. John does not say this! He simply called it a supper. John gave the true timing for the Passover (John 18:28) which according to Matthew, Mark and Luke had already been eaten Matthew, Mark and Luke's timing for the Passover was based upon how the Pharisees (the independents) calculated Passover interpreting the14th of Abib at even to mean as the I3th ends and the 14th begins. But the timing John gave us was when the Sadducees (the church conference) met (John 18:28), Which was Abib 14 between the two evenings (3:00 p.m. on the sundial) for He connected us to the Old Testament prophecy in Exodus. "And he that saw it bare record, and his record is true: and he knoweth that he saith true, that ye might believe. For these things were done, that the Scripture should be fulfilled. A bone of Him should not be broken" John 19:35,36. [see Exodus 12:46].
“This is the disciple which testifieth of these things, and wrote these things: and we know that his testimony is true." John 21:24. "The testimony of YAHUSHUA is the spirit of prophecy." Revelation 19:10. John was a prophet! He had the spirit of prophecy! The others Matthew, Mark, and Luke were not prophets. They were just recorders. I am not saying that their record is uninspired. Their story is inspired. They heard at the mouth of others, for they themselves were not present. Matthew, Mark and Luke stated that YAHUSHUA ate the Passover with His disciples, on Thursday evening/night, and true they did eat a Passover meal. But John records the real timing for Passover was on Friday evening/night. The timing for the real Passover has been a quest for centuries. The Passover controversy existed in Europe as well. The "Celts themselves declared that they followed John.” The Celtic Church in Britain p.95
The picture that John painted was that YAHUSHUA was Passover Lamb “The Lamb slain from the foundation of the world." Revelation 13:8. Which shows that the Feast days were set up from the foundation of the world. James Arrabito produced a video about the Feast Days, the name of it was called "Foundation of the World."

"John was cast into a caldron of boiling oil; but (YAHUSHUA) preserved the life of His faithful servant, even as He preserved the three Hebrews in the fiery . . .John declared, My Master patiently submitted to all that Satan and his angels could devise to humiliate and torture Him. He gave His life to save the world. I am a weak, sinful man. (Messiah) was holy, harmless, undefiled. He did no sin, neither was guile found in His mouth." Acts of the Apostles p.569,570
McEwen "son of Ewen”, Polish Iwan, Russian Ivan, Spanish Juan. Romanian Ioan, Greek IwannhV (Ioannes) forms of John. Ewen like Owen means young warrior. This famous name around the world, was the result of a man who loved YAHUSHUA and became a warrior for the truth "And hereby we do know that we know Him, if we keep His commandments. He that says, I know Him, and keeps not His commandments, is a liar, and the truth is not in him" I John 2:3,4.
