Looking for Turvey of Australia

My name is Ngaire Mcneill (maiden name ADLAM).I was born at the Opunake cottage hospital 1953.Parents Thomas and Joan ADLAM(My Father took his Mothers maiden name)I have 4 Brothers and 2 sisters.Dad was born 14/12/1932 and died 15/1/1986,the family lived in Taumarunui,New Zealand.My Grand mothers name was Clara Daphne ADLAM.She had 4 children,3 daughters,Agness,May,Daphne and my Dad.
My granmother met this TURVEY man and had 4 children,they never married,apparently he had a wife and family living here in Australia.He went to New Zealand for work.He was deported back to Australia when he got into some trouble leaving my grandmother with 4 young children to bring up on her own.She died a couple of years later,the children were put into foster care
I do not know his first name or have any dates,i wonder if my Dad was named after his Dad THOMAS FREDRICK,had red hair and was a drinker.
