The '90s Flash was named Barry Patrick Allen.
Ah, okay. Still, if Henry Allen and Jay Garrick could be the same genetic individual with different names due to different life circumstances (something also implied to be true of John Diggle/John Stewart), then there's no reason Barry-90 couldn't be another doppelganger whose parents just chose his name differently. Given that Earth-1 has multiple doppelgangers of Earth-90 residents -- Tina McGee, Anthony Bellows, Julio Mendez, Trickster, Prank -- it logically follows that Henry and Jay are meant to be Barry-90's doppelgangers. After all, two of the three lookalikes ended up as the Flash of their worlds (and battling a version of the Trickster); on Earth-1 it just came a generation later.
Furthermore, to those who've been saying that Marv Wolfman considers abolishing the multiverse a mistake I'd pay particular attention to the question that specifically refers to that very issue (spoiler, he doesn't).
I never said that. I said that
I consider abolishing the multiverse a mistake, and clearly the editors at DC eventually did too, since they restored it some years later. I also said, separately, that I'd heard a quote from Wolfman saying that the only good thing about the
Crisis story itself was the paycheck -- which, whether my memory of the quote is accurate or not, was
not about the decision to eliminate the multiverse but about the quality of the actual
writing of the story. You're confusing two different topics: One, wheher CoIE is good as a work of fiction in and of itself; and two, the way that subsequent works of fiction in the decades to come were affected by it or undid its effects.
The decision of DC's editors that eliminating the multiverse was a mistake was, naturally, a decision that was arrived at gradually over many years, since it took that long to restore it fully. So it's not about Wolfman, since he wasn't the one making those decisions years or decades down the road. But the advantage of doing an adaptation later on is that you don't have to repeat the mistakes of the past. You can learn from the
whole process your predecessors went through and just skip right to the end rather than recapitulating the whole thing from the start. And the end of the process, the final outcome of the experiment, was the choice to restore the multiverse to the comics, because DC's creators decided the franchise was better off with a multiverse than without one.
