> The grandmother who had charge of them in their youth, Bertha Krakowsky, belonged to the noble Kolowrat family of Bohemia and was married to a member of the Austrian princely House of Colloredo-Mannsfeld when her pregnancy by the African American tenor Roland Hayes caused her to forfeit access to her four elder children, her palatial homes in Berlin and Prague, and her moral reputation in European society. She tried to sustain her episodic relationship with Hayes after her divorce and his return to America, but declined his offer to legally adopt and raise their biracial daughter, who would become Igor and Grichka's mother. Their coal burning grandmother destroyed the family genes, that's why they look so fucked up.
