Sorry, but I don't understand your question, and, judging from the lack of replies from the other forty-odd people who have looked at your post, neither do they.
A religion newly founded by you always brings a pop-up display naming the religion, and the icon for that religion then appears in the city bar and on the city screen, top right. Of course it's a religion "from the original game", since no new religions have been introduced (unless somebody has modded one in).
This does not happen when a religion spreads to another city or is founded by a rival civ: this brings a popup message during the inter-turn display, and again the icon is added to the city.
