Fidan´s wedding - Fidan´ın düğünü  or Fidan´ın düğün

many thanks

It is Fidan´ın düğünü

If there is a suffix after first word (Fidan´ın), the second (düğünü) always has a suffix too.

cok tesekkurler

I was stuck on this one recently too. I guess both the possessor and the possessed need to be marked in Turkish.
