I am looking for the Australian daughter of Andries van der Wal. She probably calls herself Rhonda Grogan(?).
The daughter is the fine result of a relationship between Andries and the daughter of his landlady. During WWII and short after that, Andries lived in Australia. Unknown where.
The relationship started when the ship on which Andries van der Wal worked had been docked in one of the harbours of Australia.
