I have downliaded the latest version. I can zoom into various parts.
He is an honest man, gives age as 40, born Molong N.S.W., divorce absolute with that effective date, etc.
So the question becomes :
Why can we NOT find his NSW birth rego.

Some answers include

registered under a different name

not registered

registered at Molong Court House, but the quarterly/annual return was not submitted and/or not procesed by Reg General at Sydney HQ ( until after WWI there was NOT any admin rule at HQ to check WHY no returns from any rural district.

in mid 1970s Reg General dept insisted on ALL the original ledger books being recalled from every deputy registrar. Some rural senior officers ummm took no action to comply.

when EDP System initially set up, if a card mangled itself, noone knew how to recognise what data list
I could add many more "excuses" ... but we need solutions.
I am on e reader, tiny screen.... 1 finger typing.
My ancient rellies suggest:
Use LESS is more technique on NSW on lline birth search.
Use Jack* for surname.
Search one year at a time and one bdm district at a time.
So Molong is one diiatrict. Look also at Wellington; Forbes; Coiwra; Orange; Mudgee; Bathurst; West Macquarie; any Central West locality with a Court House during the ten years before and after he was born.
Also consider he may have Aboriginal heritage at a grandparent or earlier generation.
My ancient rellies include retired NSW bdm senior bods, they will clear their committments for early next week to give your eyes a rest.
JM sorry for possible typos, por grammar and silly spelling. GOOD LUCK.
