A Kohen of Proven Yichus

Rav Alter Kahana of Ziditshov/Spinka, the son of Rav Yosef Meir, testified that the family has a pedigree of yichus that traces its family tree directly back to Rav Yaakov Yosef HaKohen, the mechaber of Kuntres HaSefeikos, who in turn traced his lineage directly back to Eli HaKohen.

Rav Yosef Tzvi Dushinsky, the chief Rav of Yerushalayim, used to send everyone who asked which Kohen to use for a Pidyon Haben to Rav Yosef Meir Kahana of Spinka, because he was a Kohen with a strong pedigree and reliable yichus.

Once, an elderly Jew, a bechor (firstborn), came to Rav Aharon of Belz, complaining of pain, suffering and various calamities. The Belzer Rav told him to go and redeem himself a second time, using Rav Yosef Meir Kahana as his Kohen. And so he did. From then on, he was transformed into a new person.
