There are not as many Adult Children of Alcoholics and Dysfunctional Families meeting as AA, but they may address some underlying issues better, IDK. I found the fellowship in ACoA very reassuring and helped give me somewhere to go to be with people. I'm not an alcoholic so wasn't trying to address that, just the Dysfunctional Family part.

They have some online, too, I think, if that's of interest.
