The website page http://www.zabludow.com/chosenpagesslonimsky.html is the English translation for A.S. Hirshberg's article about Chaim Zelig Slonimsky, "Chaim Zelig Slonimsky was born close to the end of winter of 1810. His father, R. Ya'acov son of Rabbi Binyamin Bishke, was a scholar; they used to call him R. Yankeleh Slonimer because his origin was from Slonim. Chaim Zelig Slonimsky is the grandson of R. Yekhiel Neches, founder and owner of Beit Hamidrash (house of study/academy) in the Jewish Street in Bialystock, and it is named after him."
