The validity of original Non B is 3 months start from 1st day you arrived in Bangkok, then 30 days before your Non B expiry date we will proceed one year extension. (Tentatively mid of January 2016)
The immigration office will not confirm a permit of stay until we proceed the Non B one year extension.
Alternative option; Your family may apply for tourist visa and we convert their to Non O at Bangkok immigration after you had permit of stay (one year extension) and they may need to fly out sometime during this procedure.
Btw, do you have skype ID ka? if you do, please add me (tasanan_mr) then we can discuss about this matter, Thank you.
