I don't think it is a coincidence. I think your Catherine married a much younger man and it is quite evident she altered her age.
A cert or two would help you. Are you aware of the information on certificates in Victoria?
From the Resource and Offers board..
Deaths Date and place of death;
name and surname;
occupation of the deceased;
sex and age;
cause of death,
duration of illness,
medical attendant by whom certified and when he last saw deceased;
name and surname of parents (if known) including mother's maiden surname signature, description and address of the person who gave the information; signature of deputy registrar, date and where registered,
when and where buried,
undertaker whom certified;
name and religion of Minister, or names of witnesses of burial;
place of birth of the deceased and how long he or she resided in theAustralian colonies or states (stating which),
name of spouse,
place of marriage,
age at marriage;
names and ages of children of the deceased.
Marriages Date and place of marriage;
name and surnames;
conjugal condition, whether bachelor or spinster, widow or widower, stating date of decease of former wife or husband; children by each former marriage;
birthplace; occupation;
age;
residence (present and usual); parent's names of each party (including mother's maiden name) and occupation of father; signatures of the parties and witnesses;
signature of Minister. Prior to 1963 the date of termination of previous marriages of the parties is also shown.
I think my choice would be the marriage certificate as the information is given by the people themselves not a third party. The highlighted information would either prove that this Catherine is yours or eliminate her from your search.
Address is from CWGC record for her husband. I am not familiar with the area - is it well known?
A suburb of Melbourne. Search google maps and street view.
I have done a little more research and found a George Albert
WARD at Kalimna on the electoral rolls with a Michael and Sarah WARD in 1924. There is a George Albert
WARD born to Michael
WARD and Sarah
JEFFERSON in 1899. He is on the electoral roll with occupation farmer until 1954 and then he moved to Lakes Entrance and eventually Bairnsdale, where he died.
