Thank's a lot for the information. Although, unit 132 was last updated/added in 2018, I'm not sure if there will be more soon.

Contacting the Archiwum Państwowym w Warszawie seems to be reasonable.

Hi,

I'm looking for a Marriage certificate from 1917 Augsburg Confession from Warsaw.

I saw that there is a "Akta stanu cywilnego parafii ewangelicko-augsburskiej w Warszawie" at https://www.szukajwarchiwach.gov.pl/de/zespol/-/zespol/96467?_Zespol_javax.portlet.action=zmienWidok&_Zespol_nameofjsp ...
