Have discovered that name is old and from town of Radawie in western Poland. Town mostly destroyed in 30 yrs war in 1615. Suspect that diaspora and part of family went down major trade route and settled in radawa (not too far in the woods). Father, Vincent born in 1909, baptized in tomaszow lubelska, emigrated to michigan but not sure if his parents lived in radawa or other nearby community in eastern Poland. As Radawski name is from 1455AD register suspect that come from residents who lived in radawie and not knight who was given land. Thanks. Dan Radawski.
