Reb Yakov Yisroel Halberstam (Yankel) was the youngest great grandson of the Sanzer Rov ztvk"l. Born in 5695/1935, He was the son of Reb Yecheskel Shraga Halberstam who was the son of Reb Yitzchok Yeshaya (Shaye'le) of Tsehchoyv, both of whom were murdered by the Nazis and their collaborators during WWII. Reb Yankel's mother Rivka Beila was a daughter of Reb Bentzion of Bobov HY"D, which made him a nephew of Reb Shlomo of Bobov II. Reb Yankel passed away on Erev Rosh Hashonoh. We were informed of his passing by his daughter. The above photo, despite it being listed as that of Reb Shaye'le, of Tshechoyv is actually that of the Tzeshinover Rebbe, a nephew, or great-nephew of Reb Shayele. This is obvious from the writing on the photo, as well as to those who knew his son in Boro Park. The strong features are very visible amongst later generations as well.
