Actually, there is quite a bit written and known about Moses, including the members of his family. If you were able to read the Torah, as well as the other Jewish scripture, you would know this.
You should not be so quick to assume ignorance of those who disagree with you. I am quite familiar with the Old Testament.
If you had read correctly what I wrote you would have seen that I was responding to JadeEmperor's statement:
There is actually very little that is known to be a fact about the historical "Jesus" existence besides the so-called "New Testament".Much is known about both Moses and Jesus, from the Old Testament in the first instance and from the New Testament in the second. My point was that testimony about Jesus in the New Testament is just as reliable as that about Moses in the Old Testament.
