This is the last thing I have to do before I can release my town mod, that I have been working on over the last two years. I had this same issue in my Unique Taverns Winterhold mod, but for the life of me I cannot remember exactly how I fixed it.
Basically my moving in game Skuli when I revamped the tavern broke some links and now Skuli thinks he is an orphan.
I asked in my WIP thread when it was open...

But am still stuck. I opened up my Old Hrolden mod in TES5Edit and loaded it up, which loaded Hearthfires as well as it is dependent on that....
This is what I found under http://i110.photobucket.com/albums/n99/Shezrie/HearthfireSkuliREF_zpsb6c17ff3.jpg
This is what is under Skuli's ID in my mod http://i110.photobucket.com/albums/n99/Shezrie/ShezOldHroldanSkuliREF_zps5957f589.jpg
I removed Skuli from my mod, which resulted in http://i110.photobucket.com/albums/n99/Shezrie/HearthfireSKuliafterremovefromOldHroldanmod_zpsc52cdff9.jpg. But ingame the issue is not fixed.
Other then basic cleaning, removing adding etc my knowledge of TES5Edit is limited. Could someone please give me step by step instructions on how to fix this so that I can get this mod released today?
