Since the game was released, gamers have been trying to find the missing Princess in RDR 2, but no one has been able to do it. The fact that it existed, you can find out about the trading post of Van Horn, there is an announcement about its disappearance. But the information on the poster has become outdated, since 15 years have passed since the disappearance.
There are several references to Princess Isabeau in the story version of RDR 2. Near the Elysian reservoir, you can find a tent, and there will be a man near it who will tell you that he is searching for it, there is an assumption that it is located in Van Horn.
Players also paid attention to one of the characters in the bar, they thought that this woman is the once-disappeared Princess. She has a resemblance in appearance to the disappeared girl, identical hairstyles, a pendant around her neck (just the one we see in the ad).
But, here's the age of the lady looks quite older. But, nevertheless, the version that the bar is the same woman, was not confirmed, as experienced gamers dug into the game files. So until the end, it remains unknown where to find the Princess in Red Dead Redemption 2.
There is a solution after all! The creators of the game most likely just cut out the quest that was associated with the search for the Princess, this is evidenced by a file called CS_PrincessIsabeau, which is a female NPC model. Most likely this is the missing Princess. Even when running the trainers, you can see the NPC, but, alas, you will not be able to interact.
