"to Paul Wilson re: Peter the Roman"

Here is a current list of cardinal electors from Italy although not necessarily from Rome.

Although the rules can be changed at any time, in general one must be a "Papabile" or eligible to be elected pope. This means the candidate must be under 80.

All popes choose their name by which they are called, so although there are no Peters on the list, any of them could choose "Peter"

And of course this list can be added to at any time, and can be reduced by death.

This list is hyperlinked should you wish to read more about an individual.
