Is There a Prior Relationship Between Paul and Rome?

Rome wasn't a church that paul anted. He planted galatians and thessalonians, you know. So they were already established. And so he had one on one relationships with them that preceded any letters he later on had to write. Somebody else planted the church at r Rome. You can have fun stories about whomwho could it have been? Were they coming from? Acts chapter two, and going back to rore, and then, and then.
