How many Igorovychs died?
Article by M. Voloshchuk
Voloshchuk M. in 1210 Igorovychs of Chernihiv: topical issues of the reconstruction of Rus’-Hungarian relations in the beginning of the 13th century. – Studia slavica et balcanica petropolitana, 2007, No. 1-2, p. 105 – 112.
So, the new literature on the topic of the execution of the Igorovychs is quite significant, but it does not contribute anything new to the understanding of the subject. Except that in these articles you can find links to other articles on the topic, including the most recent ones.
