Her name was Betty Ross I guess- en.wikipedia.org/wiki/Golden_G… I remember Betty from Cap, but not her as Golden Girl, although I guess that was near the end of the original Captain America series.I have a book of the original few Captain America comics and could swear Thunderbolt and Betty Ross from the Hulk were in it at the army base with Steve and Bucky. I'll have to read it again, because maybe I just don't remember correctly. The wiki says differently, that both characters were created in the 1960s, but that a different Betty Ross was in the early Cap comics. I guess it seems unlikely Marvel history was altered later without them mentioning it.I had assumed that Stan Lee just brought Betty and Thunderbolt into Hulk- like Namor came to the FF, the circus villains came to Spider-Man (they were in the 1940's Cap first I seem to remember), a Human Torch in FF, and Cap into Avengers. But maybe not.
