No, they wouldn't name their daughter Halo. It's never been really even used as a name, nor likely to be, that's why the list is so ridiculous. The Baby Centre, whoever they are, clearly picked them at random and added some Game of Thrones names for good measure.
Also some 'old' names, probably 'cos they come around again, the old names, don't they, hun' Not Beryl, and in 2016, though!
