I simply asked Google, 'When was Steve Rogers woke up from the ice' and this is what I found.
"She didn't say - but neither did she actually marry. The family photo was a fantasy created by Peggy to help her deal with her loss of Steve Rogers. Peggy Carter is married to Howard Stark. This makes her Tony Stark's mother."
How the hell does this even relate to Steve waking up from the ice!?!? I mean, come on!!!
