Léo Golovine advises:
the princess Anastasia of Ryazan (Anastasia Ivanovna) and her only brother Oleg Ivanovich, grand-prince of Riazan (Oleg Ivanovich, Grand Prince of Ryazan) are shown as children of Ioann Korotopol, prince of Pronsk & Ryazan (Ioann Korotopol, prince of Pronsk & Ryazan) and having a sister, Sofia of Ryazan (princess Sofia Ioannovna).
In fact that is NOT true.
The mistake is VERY OLD, basically 2.5 centuries after these events in XIVth century, Moscow official court genealogists (who composed the fundamental source called "Gosudarev Rodoslovets", which does have some errors, put this prince Ivan (Ioann Korotopol, prince of Pronsk & Ryazan) as their father, because 250 years later the genealogy of the Riazan branch of Riurikids, the least known, was not very clear for them, in addition there were TWO princes called Ivan in the region then... So they were confused).
Already in 1850s it was clearly proved by the historian Ilovayski that the REAL father of them is in fact Ivan Aleksandrovich, Grand Prince of Ryazan - a cousin.
All the modern Riurik specialists know that. For instance, Pchelov, in his fundamental book on the genealogy of Riurikids, writes all that CORRECTLY, without even mentioning that for 2 centuries there was a mistake on this matter. (As for Wikipedia, it does mention the former "officially accepted" version, and explains that it was proved to be a mistake, cf.

Why is it shocking?
Because Korotopol (shown as father of Oleg and Anastasia, which is false) personally KILLED their (real!) grand-father (Alexander Mikhailovich, prince of Pronsk). So instead of having their REAL father (Ivan Aleksandrovich, Grand Prince of Ryazan), they have the killer of their grand-father. Totally immoral.
