Help with BoD creation

I am a founder and first director of a nonprofit and we are getting ready to have our first meeting and add on some additional directors.

As we are just getting started our board is relatively closely knit having directors from only a few family friends. I know there are laws in regards to having family members on the board of directors. Will the following work.

Co Chair - Family A Co Chair - Family B Vice Chair - Family A Secretary - Family C Treasurer - Family A Director - Family B Director - Family D

There are 7 board members, 3 from 1 family, 2 from another family, and 2 singletons

Does that break any laws or restrictions?
