I found many of my Upper Silesian ancestral family members' Catholic church records --baptisms, marriages, and deaths in the curia of the Archdiocese of Katowice. The custodian of the archive records there is a very capable and helpful gentleman, Dr. Wojciech Schaffer, who communicates in both Polish and English. For a little less than $20.00 per document, he will render magnificent official transcriptions of requested church documents of baptism, marriage, or death. The archived records are from medieval times to about the World War II era. More contemporary Catholic church records are maintained by the parishes where the events were officiated.
