Same Yahrzeit

 

In the פיוט of the first day Shachris Rosh Hashana (אבן חוג) it says "סלוף דינה ביהוסף להנחות" The Chasam Sofer quotes from the ספר טיב גטין who the Ch. Sofer  quotes from a מקובל, who said, that when יוסף was in לאה's stomach his name was יהוסף and when דינה was in רחל's stomach her name was דין. After the mothers were switched, יהוסף lost the ה and became יוסף and דין received that ה and became דינה ---- Actually, the טיב גטין doesn't quote this from an unknown מקובל but quotes this from his Mechuten הרב לוי יצחק מברדיטשוב זצ"ל. In all probability, the Chasam Sofer never heard of the קדושת לוי and therefore refers to him as  an unknown מקובל אחד. This Shtikel תורה is very unique. All three names mentioned (R. Levi Yitzchok Barditchev - R.Efraim Zalman Margolis- טיב גטין & The Chasam Sofer)  were all Niftar on כ"ה תשרי
