Okay okay....you’re probably right. So why would he take his mother’s last name, any idea?
His parents divorced when he was quite young and he lived with his mother and her parents. The father was never really in his life and though he was named for him, I'm guessing that he didn't care to be associated with that name, at all and probably didn't/doesn't like him. Hence the named change. There may be other reasons, too, for the name change, but this is the story de B. puts out for public consumption.
