Looks like a great site, from what I can translate using Google Translator. Unfortunately, I do not speak Polish and cannot read most of it. I am searching for records relating to Balbina Lewandowska born around 1890 in Krzemien, Kowal, Gostyn. She emigrated to the US and married Jozef Kaminski in Philadelphia in 1907. I do not know if she died in Philadelphia in 1909 or if she returned to Poland in 1909 and died there. I know that her infant son, Franciszek Kaminski, was raised by his Lewandowski grandparents in Kowal until he returned to the US. Do these names or places relate to any of your Lewandowskis?
