Who are the possible "Sword[s] of the Morning"?

The title Sword of the Morning is conferred upon a worthy member of House Dayne ¹

• the most recent and notable one being Ser Arthur Dayne .

The Sword of the Morning then also becomes the worthy wielder of Dawn

• the ancestral greatsword of House Dayne.

Currently, the whereabouts of Dawn are unknown. But it is assumed that the Sword is in Starfall , or in safe keeping at the hands of the Daynes elsewhere.

Who is the most likely candidate for Sword of the Morning?^✪

The person must be:

• A great Knight


• Of House Dayne


• "Worthy"
  
  
  
  • Let's say brave, honourable and skilled
  
  
  
  


• Not necessarily the Lord or heir

The candidates which spring to my mind are:

• Edric "Ned" Dayne
  
  
  
  • A little bit young, but he's pretty much the same age as Jon Snow
  
  
  • Arya has met him and he seems quite brave and honourable
  
  
  
  


• 
  

  Gerold "Darkstar" Dayne

  
  
  
  
  • Seems untrustworthy
  
  
  
  
  
  
  • Calls himself "The Sword of the Night"

^{✪ This question has no canon answer at this point, but given the criteria, we can at least narrow the candidates down using canonically sourced attributes.}

^{1. From an interview with G.R.R.M.}

^{asked about the Daynes and the Sword of the Morning, asking how that title is decided. George said the Sword of the Morning is always a member of House Dayne, someone who is deemed worthy of wielding Dawn as decided within the House, that whoever it is would have to earn the right to wield it.}

^{2. I know Dawn isn't a Valyrian Steel blade - it is made from the "heart of a fallen star" but is compared to VS.}
