 : The guideline you're probably looking for is WP:COMMONNAME, the reason we use "Bill Clinton" instead of the longer form is that that's the form that's usually given in recent reliable sources, etc.  If post-transition coverage has preferred "Laura Grace" to "Laura Jane Grace" then that guideline would say we she should do the move.  However, most of the coverage I've seen has used "Jane", so, without more evidence, I'd oppose the move.   20:56
