I can give you some infos about your Surname. My boyfriend is Polish and his name is Andrzej Kaczkowski. He lives in Warsaw but he is originally from BROK, 92 km far north east of Warsaw, where his family still lives. Nearby Brok there is a village called Kaczkowo where this surname comes from. If you would like to know more please write me. Waiting for news, many greetings Claudia Romagnoli Kaczkowski PS: I'm from Italy, but I'm going to live in Poland in August. I'd like to be in contact with you!
