How was it found?

The reason some don’t write the name Chayim is because it seems to have been added later, and therefore when he brought down Rebbi Dubov he was perhaps not called by it.

Proof to the fact that it’s a name that was added later: He has two grandsons named after him, (sons of Reb Betsalel and Reb Berke); whilst Reb Berke’s son is called Chayim Shneur Zalman,Reb Betsalel’s son is only called Shneur Zalman.
This surely proves that even though his name eventually was חיים שניאור זלמן, his family didn’t necessarily see it that way.

Would love to hear

Rebbi Dubov was not just the Rov, he was a Baal Koreh every Shabbos and Yom Tov plus megillas ester and Chazan for musaf for all yomim tovim and Yomim Noroim plus kol nidre and neila. He was a talented Baal menagen; so for example the Rebbe’s Ato vechartonu was sung in our shul in chazoras hashatz long before the Rebbe taught it. We learned many memorable nigunim for hallel and musaf still sung in my family.

I was brought up in the Adas Yisroel shul and R’ CSZ Klyne was my Uncle Lazer z”l Klyne’s father.

Well, will you share this nice backstory !!! Always interesting to hear nostalgia of chassidim especially those who assisted and made life easier (begashmiys) to the Rabbayim. Please share !

Rabbi Dubov (or as he is known in Manchester – “Rebbi Dubov”) was the rov of the Addas Yisroel Nussach Hoarizal shul untill his passing in 5737.

He was brought to Manchester by Reb Shneur Zalman Klyne, The Parnas of the Addas shul, who knew him from his time in Riga.

He was brought to assist the then rov of Addas shul, who was also the Av Beis Din of Manchester, Rebbi Rivkin.

After Rebbi Rivkin away, ערב יום כיפור תש”ח, Rebbi Dubov took over as rov of the shul.

When they parted, the Rebbe Rayatz told R Yitzchok we will meet again.

The met next at the yechidus before the wedding of R Yehuda Leib Dubov obm, who was married Zayin Shevat.
