My name is Stefan Lorentz. I am living with my family in Zamo¶æ (near Tomaszow) in Poland. I found Your post when I search on Google word: "Lorentz". I am looking information about my credible family. Very credible, that they are from France, because most of my oldest ancestors who died near 1700 year, have french names like a "Leon Lorentz" or "Fryderyk Lorentz".
