I have read about a Gubernii caled Kule which apparently was situated in the Warsaw area
No, it says (from the scanned piece) :
...wieś Kule, Gubernia Warszawska..... -.... village
Kule, in the Warsaw province...
Years ago, this village could become part of a town or city nearby.
Why don't you put all the question in one topic, it would be easier to answer looking at the scanned document.
Hopefully some-one might be able to shed some light.
I don't know if you notice but in the document there is church name and street name.It could link to some important details.
Church name: Kościół Św. Krzyża (Holy Cross Church)
Street name - Nowy Świat (New World Street)
Look:
