As a nerd of the phrasing here’s some tips- Lords are “My Lord”/Ladies are “My Lady”, Dukes/Duchesses are “Your Grace”, then for royalty it’s “Your Highness”. If you need terminology help then I’m your person! So Lord Harlowe would be a Duke if you were to use “Your Grace”
Also Lord Willow is m favorite- Nice and gentle/caring :) Yes, men
