Rabbi Dovid Shlomo Novoseller, a descendant of Rabbi Levi Yitzchok of Berditchev (Kedushat Levi), Rabbi Samuel Eidels (Maharsha) and Rabbi Yechezkel Landau (Noda Biyehuda), was born in Yarmolintsky on Aug. 19, 1877, and received semicha from Rabbi Moshe Noson HaLevi Rubinstein, Av Beth Din of Vinnitsa.
Rabbi Dovid Shlomo Novoseller turned 10 years old in 1887.
This is definitely correct because he was born in 1877, so he would turn 10 in 1887. I think the system is bad at calendar math.
