Is there any archives on illegitimate births from 1918

Is there any archives on illegitimate births from 1900 onwards

Orphanage records, probably State and Territory by State and Territory? Also child migration records from Britain in the NAA. It all depends on what you want. Do you have a particular person in mind?

Yes, my mother Betty Dale Harmer , born 1918 Wagga Wagga

I assume that this does not concern anything like an adoption or any other special circumstances, so I’m not sure why you would think that there were archives specifically for children whose births only had a mother listed?

In this case there is a normal birth certificate available:
Name: Betty Dale
Registration: number 29092/1918
Mother’s given name: Margaret
District: Wagga Wagga

Thank you so much for the reply, I now have a copy of the birth certificate, would there be a adoption certificate available as Betty was adopted to Walter James and Ethol Maude (nee Stockton) Harmer about 1919.
Kind Regards

I’m not a specialist but I believe that NSW official adoptions didn’t start until abt 1923 and that earlier"adoptions" would have been an unofficial process.

However, if Betty had been e.g. a neglected child , NSW archives might have a file on her. (I can’t see anything online, but that doesn’t mean there isn’t anything in the physical archives for her)

Maybe somebody else here knows more regarding this subject …
