Did Solomon have a son?
Disappearance of Sky Metalwala
Solomon said he believed that his son was alive, but perhaps not in the U.S. In spring of 2011, after the visit to the doctor that was the last independent record of Sky's presence outside of Biryukova's household, he recalled that her estranged father came from Ukraine to visit her. He wondered to the "Weekly" if the older man could have taken the boy back to that country with him at the time. But in 2013, he said that he did not know how that could have happened.
Solomonia Saburova
Sigismund von Herberstein asserts in his "Notes on Muscovite Affairs" that she was forcefully taken to the convent, whereas the Russian chronicles tend to underline Solomonia's submission to the sovereign's will. There were rumors that Solomonia had given birth to a child named George within the walls of the monastery. She died in Suzdal in 1542.
