Moses, or meses, means child, or son, even kid. So Ramses would mean son of Ra, and Tutmoses would mean son of Tut.
Why would Tutmoses (which ever one of them, there were several, IIRC) would be on the same level as Osiris, the god himself?
And why, in the name of God, or Ra, or Tut, or whomever, would he want to be known as brother Mo?
