So in Lomza, we see that "Abram" was the most popular name for males, and "Sora" was the most popular name for females. The Biblical patriarchs and matriarchs topped the lists: Abraham, Isaac and Jacob (recorded in civil records in the Yiddish versions: Abram, Itzik, Yankel), and Sarah, Rachel, Leah and Rebecca (Sora, Ruchl, Leia and Rifka) are all within the top five positions.
For females, we see that purely Yiddish names occurred often, such as Feiga, Sheina, Gitel, Bayla, Liba.
