What is Saint George's real name?

Answer 1

George is his real name. I am sure it was spelled differently in Latin or Greek but, whatever, the name was still George. At the time there were no surnames used. That did not come into use for hundreds of years. If George had any other names, there is no record of them.

Answer 2

Saint George's real name was likely Georgios, as he is often referred to as Saint George of Lydda or George of Cappadocia based on his origins. He is one of the most famous Christian martyrs and is recognized for his bravery and faith.
