So I think Sophie's father could be two people. Either Tiergan or Elwin.
Elwin:
Elwin cares about Sophie so much. He and Oralie wouldn't have really known each other either so they wouldn't find out about their secret connection to the Black Swan. Also he seemed really hurt when Sophie was scared of him at first and I feel like if he had no connection to her seeing as he just met her he shouldn't have been that hurt.
I also just really like Elwin and want him to have a bigger role so that might be swinging my opinion just a little...
Tiergan:
He's blond. He's a super strong telepath. That's about all I've got but if you want more reasoning go read classicalbibliophile's oneshot book where they gave a lot more reasons.
If you think there's someone else who may be her dad let me know :)
