The Bible does not have a record of people changing their names from a pagan first name to a “Christian” first name.

There's always (Simon) Peter. And don't forget (Saul) Paul. Others?

[ArrogantBustard]

God changed Simon ==> Peter, much like Abram ==> Abraham. Does it actually say how Saul’s name got changed to Paul? I can’t recall ever seeing that.
