It wouldn't surprise me at all to find out that the names Christian and Christina actually had origins that predate the Christian religion.
It does.
It must be remembered, that "Christ" itself is a Greek iteration of the Hebrew word "To anoint", or "messiah". It gained popularity in Greece after it became Christianized, but the name actually existed in earlier forms in Egypt.
And also, the name was very popular in Europe among the Jewish communities, especially in Sweden during the 17th century. That is because Queen Christina of Sweden (R - 1632-1654) essentially pressured Pope Clement X to forbid the chasing and harassment of Jews. And also refused to allow any persecution of Jews in any lands she controlled (or had influence over).
A Kingdom which during that time covered parts of what is now Russia, Germany, Estonia, Latvia, Poland, Finland, Norway, and all of Denmark. And the name continued on among many families. And another common name from that region and era for both first and last names was Kristal. Also a name very easily anglicized to Christine.
And for Yeshua, that today mostly translates to Joshua. Many old Coptic texts list him as Yeshua Ben Yosef or Yeshua Bar Yosef (Joshua son of Joseph).
When reading the New Testament, it must be realized that a lot of names were likely fictitious and of symbolic importance as well.
Most know of Barabbas, but most likely do not know that the name literally translates to "bar Abba", or "Son of the Father".
Many of the names from the New Testament are quite revealing, when translated into Hebrew, Aramaic, or era versions of Latin.
