You can bring your family here eventhough your wife uses her maiden name (I too use my maiden name), as long as you have certificate of marriage showing the name of your wife and of course yours also. If the church marriage certificate is attested in your Embassy, I think its ok. But still, please double check with your L.O.
If the company is the one to process everything,they will tell you all the requirements.
All the best in your plans....
