Assistance in finding Piontek connection

[MLogan]

Hi I’m from Australia and I’ve been trying to find information on my great grandmother’s Anna Gertruda Piontek parents.
Unfortunately I have very little information, other than:
- Anna was born on 14 Feb 1906 (unknown where)
- both her parents died when she was young from the Spanish flu
- she married my great grandfather Richard (Ryszard) Philipp Winkler in Tarnowskie Góry in 1924.
I’ve exhausted all online searches I can think of, so any hints or help on how I could find her family would be much appreciated.
