Would like to find information on my father’s family. His name was Alfred Josef Bursig, he has two brothers Herbert and Paul and a sister Elizabeth (polish spellings for names probably needed.) They had children and I know their names are Gretel born around 1950,Barbel born 1958? and a few other children I don’t have names of, unfortunately. They lived around Bytom area. Their grandmother ‘s name was Martha Agnes Bursig (nee Slaszok). She married Josef Bursig.
