Are you saying His original name was Yeshu versus 'Yehoshua/"Yeshua'" or that these come from Yeshu from India? And that Yehoshua was not a common name in the time of the Second Temple?
And this is something you have objectively researched and thus hold that this means Yehoshua/"Yeshua did not exist, but that the story of Christ "came from straight from Egyptian mythology" as your author (unless you are him) contends?

It is a rare opportunity to have a published author post here on FR and be able to converse on the subject matter. For that I thank you (if indeed you are Mr. Dov Ivry).
Daniel1212 brought up some valid points in his comments and links in previous posts. I will point out the Jewish tradition from which you gain your insight into the origin of the Anglicized form name of Jesus is one such Hebrew insight and opinion. For Christianity is of origin to the Hebrew/Jewish religion and such our very first members were Jews. One such opinion to our Hebrew Christian brethren is the following:
The name "Jesus" is an Anglicized form of the Greek name Yesous found in the New Testament, which represented the Hebrew Bible name Yeshua ("Jeshua" in English Bibles; Ezra 2:2; Neh 7:7). Yeshua, in turn, was a shortened form of the name Yehoshua ("Joshua" in English Bibles).
"Yehoshua" is a compound name consisting of two elements.
(1) The prefix "Yeho–" is an abbreviation of the Tetragrammaton, God's Four-Letter Name: Yod-He-Vav-He or YHVH.
In the Hebrew Bible "Yeho-" is used at the beginning of certain proper names: Jehoshaphat, Jehoiachin, Jehonathan (the "J" was pronounced as "Y" in Medieval English). The suffix form of the Tetragrammaton is "-yah" ("-iah" in Greek, as in Isaiah, Jeremiah, Zechariah, or Halleluiah).
(2) The second element is a form of the Hebrew verb yasha which means to deliver, save, or rescue.
Thus, linguistically, the name Yehoshua/Yeshua/Jesus conveys the idea that God (YHVH) delivers (his people).

You are an author/reporter therefore the link for further research if you care to do so.
Another good Jewish scholar source to expand your understanding of the firm Jewish roots of Christianity is Dr. David H. Stern. He authored the English translation of the OT and NT called the Complete Jewish Bible (CJB). Dr. Stern provides his research on the name of Jesus Christ and its Hebrew roots both in his introduction to the CJB and within the commentaries of the NT specifically Luke chapter 1.
I hope these references will broaden your horizon on the subject matter. As a reporter, I am sure you appreciate the great value multiple sources:)

The only thing I tell you is that the name by which this god is known in Hebrew and always has been is Yeshu. This a name of foreign origin and is not related to any Hebrew name. It is also the name by which the god is known by in India. The origin is plainly Hindi.
The Greek name came in as Iesous. That is a direct transliteration of Yeshu. They added an “s” to every name.
The first time we have evidence that the Jews were even aware of the myth was circa 120 when the book arrived in Greek and Meir, the sage, read it because it was supposed to have been set in Israel. He condemned the book.
What happened outside in the empire I have no idea. But the only time there were known Jewish Christians in Israel was in the period between 120 and 135. In the Bar-Kokhbah War against Rome in which 600,000 people died on both sides, the only group that refused to muster were the Christians. As a result Bar-Kokhba accusing them of cowardice and engaging in espionage formally drummed them out of the Jewish people and they have never been allowed back in.
When the persecutions started immediately after the Jews lost the war, the Christian leaders went to Hadrian and proclaimed, “we are not now nor have we ever been members of the Jewish people.” And he let them go.
