There are 82 bearers of this surname in Poland. Two of them reside in Warsaw (capital of Masovia too). My two cents: I guess your surname might hve been changed somewhen from the original form, which might have been too difficult for Americans to spell and write. Do you have any original documents? Kind regards Jozef of Warsaw, Poland
