However, this is the timeline that has been put together (not by me) but another member here:
ILONA AND WILLY DEPART AUSTRALIA ON THE SAME UT 2506 FLIGHT TO BELGIUM. WILLY WOUTERS HAS NO RE-ENTRY VISA AND CLAIMS HE IS DIVORCED. How could he get a divorce in such a short time?
1970-1 Ilona first child born (daughter EW/ER) in Sydney
1970-02-15 Ilona left Australia on UT2506 from Sydney to Belgium
1970-02-15 Willy Wouters departed Australia without a re-entry visa on UT2506 to Belgium, status Divorced (2)
More convictions in Belgium and France, for fraud, attempted fraud, breach of trust, impersonation. Various short prison sentences in France, the longest 4 years, most to be served concurrently.
IF ILONA HAS A NEW BABY, HOW COULD SHE HAVE MET ANOTHER MAN WITH AN ENGLISH SOUNDING NAME SO QUICKLY TO GET MARRIED AGAIN?
1970 Ilona married in Budapest Hungary to MJR (Reid)
IS MICHAEL J REID ONE OF RB'S ALIASES WHICH HE USED TO RE-ENTER AUSTRALIA TO CHANGE HIS NAME FROM WILLY WOUTERS WHO HAD A CRIMINAL RECORD?
1971-6-23 WW.Arrested Rouen, Discharged 21/5/1974
1971-12-09 Willy Wouters Rouen France, sentenced to 4 years prison for fraud, forgery, confidence tricks, giving false identity
1972-01-11 WW sentenced to one month for unsecured cheques in absentia in France.
1972-11-16 Willy Wouters Lille France, 1 years prison (concurrent with previous sentence)
1973-01-23 Willy Wouters Fraud 1 years prison (concurrent with previous sentences)
1973 Ilona second child born (son CR) in Hungary?
1974-01 Willy Wouters App Dousai "checks without cover" 1 years prison
1974-05-21 Willy Wouters discharged from prison.
He may have then re-joined Ilona in Hungary but where he was is unaccounted for. He could have gone back to Australia on a different passport using the name of Michael J Reid in 1974 or 1975
1974-1975?? Willy Wouters must have returned to Australia but no records can be found according to Immigration Dept. Were Ilona and RB ever really married? Has RB has used faked documents twice or did they really marry in Hungary? Has he got any divorce papers?
1976 Ilona arrives in Australia again and goes to St Kilda, Melbourne (implied from death certificate) Was Ilona’s surname Reid then?
1976-02-12 Willy Wouters changes name to FD de Hedervary.
