Question, now, regarding titles. If this little one is a boy (which I hope is is, so the Dukedom of Edinburgh will continue on for at least another generation!) it can be assumed he'll be XX Windsor, Viscount Severn, right? So when/if Edward gets the Dukedom of Edinburgh, will his children just remain as they are (Louise and possible sister as Ladies/Louise as a Lady, possible brother as....Earl of something. Merioneth, maybe?) or gain a royal rank (HRH Princess Louise & HRH Prince/ss NN of Edinburgh/Wessex/whatever)
