My gr gr grandfather's name was Jan Schlegel, he was born in 1842 or 1848 in Krokollen (Lidzbark Warminski in XVII), now Krekole. His father was Jozef Schlegel and his mother Barbara Scherde. Jan Schlegel (do not know if he lived in Germany or in Poland) had 4 children: Antoni, Marcin, Franciszek and Anna. Marcin emigrated to Brazil and there he was a professor in a University.
Other relatives were Maria Schlegel (1880) and Klara Schlegel (1881), who emigrated to Berlin in 1903.
I would be really greatful for some information about the descendants of this Schlegel family.
