#'either Jay West or Barry West' because that's the go to for alt dimension West kids.

Have you ever heard of a speedster named Carrie Allen? I read about her once, but all I can remember is that she’s Barry’s kid. I can’t find any information about her, like what earth she’s from, or who her other parent/family is. It’s been haunting me for awhile, so I figured I should try asking.

Oh yeah, this Carrie Allen?

She's from Batman & Superman Generations 2 (#3 to be specific).

There isn't a whole lot on Carrie? Other than the fact that she exists? She's Barry's kid, she's Kid Flash and she lives on Earth-3839. She later on became the Flash for that universe.

... also Wally married a woman named Magda on this earth and had a kid named Jay West. Jay took over the mantle of the Flash when Carrie retired.
