The search function having failed me again, what might have happened if Princess Charlotte of Wales and her baby survived childbirth, instead of both dying? For that matter, what would her reign be referred to as? The Second Caroline Era, perhaps? And what would her reign be like? Would she try to interfere with politics, much like her grandfather, or had that ship sailed by then? How would her being on the throne instead of the conservative Victoria effect the social mores of the era? How many children would she and Leopold likely have? If Leopold is prince consort, does somebody else become King of Belgium? When might her now-surviving son (We'll call him William IV) take the throne?
