my daughter is grown and married i never received the child support i was ordered to receive is her father still liable?

Yes, that money was to go to you to raise your child, by not getting it you, presumably, had to raise her on a more limited budget. File a motion to show cause (contempt motion) in the court where the child support order was issued. In Ohio, a party who doesn't pay support can lose his driver's license of be put in jail.
