This thread will have all of the necessary information on marriage options and how to obtain them in the Dragonborn DLC

first off i found three candidates so far:
Morwen

Type: Nord Female
Location: Windstone
How to Marry:
• 
  
  • Speaking to her gives you the option to accept a quest. The quest sends you to her home in Falkreath, Runil, to collect a special amulet.
    
  • Complete this quest for Morwen, and she will become available for marriage.

Hilund

Type: Nord Female
Location: Bujold’s Retreat or Thirsk Mead Hall
How to Marry:
• 
  
  • Speak with Hilund to accept her favor quest. Collect and give her 50 Riekling Spears, and she’ll become a possible marriage candidate.

Halbarn Iron-Fur

Type: Nord Male
Location: Thirsk Mead Hall
How to Marry:
• 
  
  • Complete the quest “Retaking Thirsk” found in Bujold’s Retreat, and you’ll be able to accept Halbarn’s favor quest in the Thirsk Mead Hall.
    
  • Collect 15 ebony ingots and 10 stalhrim samples, and return the items to Halbarn. He will then become a marriage candidate.

IF you have found more options please post on this thread



thank you

Originally someone said that it was possible to marry Saphire by taking her the letter from Mallory, but uh.. I can't test it since she refuses to speak to me in my game lol

hmmmm i will try that BUT since i married to Morwen no promises but i will let you know if you can get this letter and can deliver it to her

okay so you CAN give that letter to her BUT you can't marry Sapphire unless through Console Command

Hrmm alright, thanks!
