yichusdik- wow- you sure have yichus and I trust that you have the most important yichus- yichus atzmo! ( you probably know the story about the zero and numbers….lots of zeros have only great worth if there is a one before them!)
A couple of questions: “no full kriah at alenu on R’H'” ??? do you mean “histachavo’oh’? (BTW, the matteh efraim was a businessman, so were his three brothers..)
second , you mention the “first R.Pinchos Horowitz” do you mean the Sheloh? (who was also named horowitz)
Lastly, I never knew that the minhag (chassidim) of making kiddush but not eating in the sukkah on shemini atzeret is from rashi..that’s new to me!
