Wouldn't he only be Dowager Consort after the Nirnaeth?

I have always wondered about the military titles, particularly! It seems an odd omission.

Although in Maedhros's case I can absolutely see him refusing or obfuscating any title Fingon tries to give him for political reasons, namely "nobody else fighting for you wants to address me as 'General' or as 'Prince' and you aren't going to waste goodwill trying to make them, Fingon. Call me 'lord of the Marches' and don't mention the land grant; it'll only make them easier to deal with if they think it's a courtesy title." :P
