מאקארעווער רבי

ר' יעקב יצחק ב"ר מנחם נחום ב"ר מרדכי מטשערנאבל זצ"ל. נפטר ל' ניסן תרנ"ב. I'm almost sure I had another post on him recently. I Just can't find it by searching the blog using keywords. Maybe one of you can. If I had this up in the past I apologize. Not that I really need to. It's like you're paying me for the content...
