LOOKING FOR MY (E W WHITEMAN) GRAND FATHER THAT SERVED IN THE AUSTRALIAN NAVY

I have applied for his file and have his RECORDS & SERVICE NUMBER BUT even though we are NEXT OF KIN we don’t have his name on the birth certificate?

1 – There were at least 2 EW Whitemans in the Navy. One from NSW and one from VIC. Which one is your man?
2 – What do you mean by “we don’t have his name on the birth certificate”? Whose BC are you referring to?
3 – What exactly are you looking for?

I am after (RAN) Ernest William WHITEMAN (my paternal grandfather’s file). his brother was also (RAN) Cyril P WHITEMAN. (both deceased). My mother was raised by her mother and her fathers name was not on her birth record, yet it states to upload ID to the person? So, how do we do that if the surname doesn’t match? I have both their Service numbers but prefer not to post them here.
