Hi Gregorz,
I am Gene. My wife and father-in-law are Ciechanowskis (Cechanowski). Their family comes from Lodz, at least Walentyn Ciechanowski was born there, together with 2 other brothers, Wladimir and Konstantyn. In marriage to Francheska Ockerko Walentyn had 2 kids - Wladimir and Yadwyga.
Would you have any leads to the above in your genealogical tree?
Thanks for eventually sending it to me to
