If a 16 year old girl and 17 year old guy with a child get married in Georgia without parental consent would the marriage be recognized in Wisconsin?

You will not be able to get married in Georgia without parental consent or a court order.

From what I know, it doesn't matter what state you go to once you are married. The state of Wisconsin will not look at the circumstances of the marriage... it will only look at the marriage itself. So I would say that, yes, Wisconsin would recognize the marriage.
