Mind you, while I was in Dublin some of the Trinity professors published an argument that she was a prostitute and that cockles and mussels was a pretence. Both code and also gave her an excuse as to why she called to various houses through the day if the guards picked her up. Mind you, that caused a lot of debate and theirs was much better backed up than this because they could show other examples of nicknames in literature from the time using shellfish, etc as nicknames for sex workers and services.

I'm not so sure. You can find numerous ribald references and graffiti that was left by various cultures over time. I've seen examples of this in Roman ruins and in Viking. I've seen some good examples of ribald rhymes from the Victorian Era. It wouldn't surprise me if many rhymes that we think of as nursery rhymes had carnal connotations or double meanings.
