Just read your post. My birth name is "Jarentowski." I have been unable to find any connection to my grandfather Franciszek who was supposedly born in Krakow around 1867. His parents were Mathew Jarentowsski and Barbara Lewandowska but that is all I can find out and I don't even know how accurate that is. So while I may not have a connection to you, I may have a connection to your wife.
