"Second Home" should work with the name varying based on the language of the fey (Irish = Gaeilge, Wales = Welsh, Scottish = Gaelic)

Irish = Dara Baile (Second Home)
Welsh = Ail Hafan (Second Home)
Scottish = Dachaigh-ùr (New Home)
Scots = New Hame (New home)

Before these become official, I would advise double checking the translations, as the above were done with Translation software.
