The Archives of Gdansk could not find the birth cerificates of Franz and Josephine’s children other than Marianna Anna and Franz Michael, twins. They searched all the years 1839-1867 except of 1853 which is missing. Franz Michael was a new relative for me though, I had Marianna Anna. They are siblings of our gggrandfather, Johann P. Reikowski. They were born 02 Apr 1852. Born in Bissau, Parish of Matarnia, Gdańsk, Poland. Catholic.
