Hi
I was looking at this one last night, the following is probably all known to you Printer?, but it does clarify some things for us:
1931 MARRIED: in New Zealand to Florence Amelia DRURY
https://www.bdmhistoricalrecords.dia.govt.nz/search/1939 TRAVEL TO AUSTRALIA, Wellington to Sydney
https://familysearch.org/search/collection/1609792From New Zealand, on ship 'Wanganella', Embarked 13 April 1939
Mr F.E. COUZENS age 44, Signwriter, b NZ
Mrs F.A. COUZENS age 36, D. D., b NZ
Master F COUZENS age 14, b America
Master C.R. COUZENS age 11, b America
1942 SIGN UP WW2: www.naa.gov.au/In Australia 14th Dec, Francis Edward COUZENS , b 7 Jul 1893 ChCh NZ, Signwriter, Painter. NOK: Wife: Florence Amelia COUZENS of Ismay Avenue, Homebush NSW. Signs up for 2 years or duration of war, whichever is the greater. Description: 5'2", Brown hair & Eyes, Fair complexion, Tattoo Lt Forearm. Engaged on the Ship 'Penguin', Rating: Constable (GS), from 4 Dec 1942 to 13 Apr 1946. Remarks: 1946 - Approval given for demobilization as convenient when passage arrangements to America are known or --- his normal demobilization date whichever is the earlier vide ….."
1943: NEWS AU http://trove.nla.gov.au/May 1943: Eldest son COUZENS, age 18, first ex-cadet of RAAF Training Corps to enlist in US Air Corps as Ground Staff Wireless Operator. Of Ismay Ave, Homebush NSW. Enlisted in ATC July 1942. Enlisted in Air Corps 'last year'; Believed to be in New Guinea.
1944 NEWS AU http://trove.nla.gov.au/Sept 1944: Eldest son , first ex-cadet of RAAF Training Corps (son of father NZEF, now member of Homebush Strathfield-Flemington NSW) to enlist in US Air Force by virtue of his US Citizenship.
1946 TRAVEL TO US: Frank, aged 53, married male, Signwriter, arrives in San Francisco with wife Florence A, from Sydney, NSW, on "Mariposa". Going to: brother C COUZENS, in Tacoma. He stated he had last left the US in 1926 and had prior to that, been 7 years in Illinois. Florence was stated never to have been in the US prior to 1946.
So to me, it look like:
1926 about: With or without the (unknown?) mother of the boys - left the US shortly after the second son was born & went to NZ.
1931: Frank married Florence in NZ
1939: The family immigrated to Australia from NZ
(that's if this was their first travel to AU)1942: Frank enlisted in Australia, and his eldest son at least, became an Australian Airforce Cadet
1942: Eldest son, enlisted in US Airforce in Nov 1942.
1943: Frank and Florence are in the NSW Electoral Rolls at Ismay Ave, Homebush
1945: Younger son also enlists in US Air Corps.
1942-1946: Frank is seemingly engaged in service on the "Penguin" - so away from home? The Boys are following their careers in the Air Force. So perhaps not a split family in the way of domestic disharmony, but rather due to the war.
The boys return to the US is very likely to have been via Services transport, and you're unlikely to find a manifest for that via the usual sources available for travel.
Do you know the name of the boys' mother?
Cheers
