Hi,
As I said in my post on this website, I'm reading much on the Ancient origins website and found this.
It's an article where the religion of Columbus is questioned. The belife is that he was Marrano, or forced Jewish converts to Catholicism.
Check it out.
To the best of my knowledge, Christopher Columbus was not Jewish. Several attempts were made to trace his alleged Jewish origin and all came up with nothing. See below:
