Originaltext - Nederländska - mijn nichtje gaat trouwen volgende maand , veel...

Bridge for evaluation:

My niece is getting married next month, lots of happiness

The last part is probably a wish: I wish (you / her) lots of happiness / luck (luck and happiness are the same word in Dutch). There is a small possibility that 'niece' should be 'cousin' but it is unlikely here.

Let me know if anything is not clear!
