Sorry for the slow reply. I have not visited this site in a while. The email address for USC Siemianowice Slaskie is firstname.lastname@example.org. Ms. Gansiniec replied to my request. After making my specific request she replied with information about what was in their records. I was also asked to establish, with documentation, who I was and how I was related to the people whose records I was requesting. After transferring some money to their account they send me the requested documents be traditional mail. I will say that I have made a follow up request for additional information and I have had no reply whatsoever.
