Ancient Origins of Name Jesus?

A while ago i discovered that the "Yahweh/Jehovah" name of the Lord/God of the Judaeo-Christian Bible seems to have early origins and has seeming possible matches in other cultures (see post here http://www.allempires.com/forum/forum_posts.asp?TID=37415 ). (Some other people have also suggested Judah's name is evidence of the name Jhvh being as early as that. Yhwh was mentioned in Noah's blessing of Shem.) I have also wondered if the name Jesus/Yeshua also might have early origins and matches in other cultures mythologies too. Below is an example list of some possibly similar-to-Jesus gods/deities names.

Firstly the name Jesus has various different spellings/versions of Jesus/Iesus, J(eh)oshua, Je(ho)shua, Jehoshua(h), Yeshua, Jesuel, Isa, Ihs, (Yeishu?)

Celtic/Roman: Esus
Slavic: Jessis/Yezda,
Greek/Trojan: Jason, Theseus, Rhesus, Zeus/Ievs, Jeoud,
Hittite/Hurrian: Teshub,
Egyptian: Shu/Yshsh ("void/empty" / "sneeze/splutter"), Osiris,
Hebrew: Aish ("man, Adam"), Ishi "husband", Jeush, Joses, Isaiah, Jashar, Isra(el), Asshur, Jew, Jeoud, Jess(i)e, Josiah, Elisha, Moses,
Sumerian/Akkadian: Ziusudra, Is(h)kur, Ishullanu, Apsu, Enzu, Gishzida, Ninazu,
Elamite: Susinak,
Iranian: Shaoshyant, Gosh/Geus,
Afghan/Kalash/Kati/Kafir: Jestan/Jestak,
Indian: Vishnu, Shiva, Isvara,
Chinese: Joss,
West African: Eshu/Edshu,

From this list we selected 4 seemingly best candidates:
- Ziusudra: Jesus/Jehoshua means "God/Lord + salvation/saves" (and he & baptism is compared to Noah's Ark/Flood, and he is the seed of the woman), Ziusudra was a flood saviour (name means "he who saw life" or "spirit"? and he took the seed of all life in his ark) The two names maybe have 5/6 similar letters (z)iusua & j(e)osua.
- Ishkur: Ishkur is a wind/storm god also connected with thunder/lightning, clouds, hail, rain, streams, and the "silver lock of the heart of heaven". His beast vehicle is a lion(-dragon), (or bull). He was the son of An or Enlil, and brother of Utu, and twin brother of Enki.
- Aish/Ishi: Ishi is from "you will not longer call me Baali "master/lord" but will call me Ishi "husband" in a biblical prophet book.
- Shu/Yshsh: Joshua was in exodus almost as early as Genesis. Joshua was the son of Nun. Joshua came out of Egypt with Moses and his name might be Egyptian origin? Shu is associated with Num/Nun in the 3 Hermes. Massey linked Shu with Moses. Shu's name means "void/empty" or "sneeze/splutter", and his nature as a god is connected with "air, dry/hot, Atlas". The "void/empty" meaning of Yshsh is similar to meaning of Abel.
It looks like Shu/Yshsh might be the most likely (though Shu himself might have earlier origins, and he might possibly match Ishkur?)
I might be wrong though because Joshua's name was originally Hoshea/Oshea before being changed/altered to Joshua.
