What Are The Odds?

Yesterday, I saw the Broadway play Irena's Vow and mistakenly thought it would be about the life and courage of Irena Sendler but it wasn't. It was about another Polish Catholic woman who saved Jews during WWII, Irena Gut Opdyke. Both recognized by Israel and also by the Catholic Church. What're the odds that within a short period of time, 2 Irena stories would be told?
