Once upon a time it was the norm The man married when he could support a family. He married a young bride to maximize that family and to be more sure that he was the father of his first child. Families married off daughters young because if they were not virgins their prospects were less bright and if they had a child already they were pretty much unmarriageable.

The Libs LOVE them some Mad Mo’...
