Dear @Naveel300,
thank you for sharing your question with the Wefugees Community.
You usually do not have to register your marriage in Germany because when you brought your wife through a family reunification, it has already been done. In addition, if you and your family have completed the requirements for the citizenship, I see no reasons, why your wife should apply separately. So, your wife can also apply for it together with you.
I hope, you have got your answer. I am a MBEON consultant. If you wish to contact me directly, you can see my profile and follow the instructions there.
Best wishes
Fardeen Noori
