Palatial Estate 1800s Warsaw

Hello,
I am looking for an house estate that was located by a beautiful park and a hotel called mirror lake hotel. This estate was lived in by the Decroix family. He was french, the wife polish. They had 2 daughters Countesses Josephine and Natalie. They left there for Paris turn of century 1889 to 1900s. No exact dates.

The mother and father died in Warsaw. The girls left. Josephine later became the Aura Scientist and Founder in Los Angeles Ca. I am preparing an autobiography and looking for history. I might believe this estate was destroyed during the lst war. But maybe there are records of it and their family.

Oh boy, would that be a find!! If you can help me or know of some who can. Please
write to me at lightalma@yahoo
God bless you

Not sure if this will help. But you should look into contacting the Potocki Family. They were part of Polish nobility before Communist times. They may have records of the family you seek. How to get in touch with the Potocki's? I don't know. If you dig deep and look hard enough you may find something.

Thanks so much for your informtion.

I will start looking.
love Dale
