More, Trish is without doubt Diavolo's child. He remembers meeting Donatella, he and Trish have the same green eyes, and it is Diavolo who can mystically sense Trish, not Doppio.

And it's best not to consider the dates of birth too much. They don't make sense. I see, and I agree with your Diavolo point. What’s even more odd though is that Doppio doesn’t remember a thing despite both of them being born in the exact same time. Maybe Diavolo was able to see Vinegar and Donatella’s romance? I dunno; the eye thing I don’t have any defence for. Maybe Diavolo when he took over began to occupy the original body. Hence he can sense Trish possibly through blood? (I tried to post this earlier, but something happened, and it didn't work, so I don't know if this will show up twice or not.)

Disclaimer: I'm not a psychologist; I'm just someone with a large interest in psychology and Google.

If we all agree that dissociative identity disorder is what Doppio/Diavolo has (just in an exaggerated way because this is JoJo), than we can pretty confidently say that Doppio is the original personality. DID usually starts at a very young age due to some/several kinds of abuse. Usually the original personality (OP) doesn't fully remember this, though, because the alter(s) form and take those memories instead. It's a protective measure, a defensive mechanism designed to protect the OP's mind. Additionally, the OP pretty much never remembers what happens when their alter(s) front, but the alter(s) remember what happens with the OP (and other alters, if there are any) fronts. This would explain why Doppio remembers nothing from his past but Diavolo does as well as why Doppio completely blacks out when not fronting. This could also be why Diavolo remembers Donatella, but not Doppio.

In regards to Trish's green eyes and ability to sense Diavolo instead of Doppio, it's possible that Diavolo had been the one fronting during that relationship with Donatella. Again, DID starts at a young age, so it's not unlikely that Diavolo could have been the one fronting. Depending on when they discovered their mom and all of that stuff happened (pre-fire, of course), you could probably believe that Diavolo wasn't as awful as he is now. A lot of experiences and trauma probably lead to his current personality.

A very good explanation of my point is this video.

Of course there are still some inconsistencies; usually the alter(s) don't age while the OP does; at least in the anime, it really does seem like Doppio's the one dating Donatella; etc. I don't think ther's a perfect answer to the question, really, and we can all just draw our own conclusions. :)
