Appositives: Restrictive and Non-restrictive - Grammar, Punctuation, and Style - kwizNET Math/Science/English Homeschool/Afterschool/Tutoring Lessons/Worksheets/Quizzes/Trivia
To me, you only have one wife so giving the name isn't restrictive; it's parenthetic, like saying 'whose name is Elin', so I'd use commas.
Mind you I'm still not clear. The only appositive I can think of right now is one I really don't know how best to punctuate:
The goalkeeper, Rob Green, was guilty of a howler
The goalkeeper, Rob Green was guilty of a howler
The goalkeeper Rob Green was guilty of a howler
[excuse the italics - can't seem to deitalicise]
