yehoshuaahron: “The Rebbe is ben achar ben from Dovid Hamelech through Shalom Shachna Altschuler (Tzemach Tzedek’s father) , an ainekel of the Metztudas Dovid (Dovid Altschuler), who in turn is ben achar ben from Dovid Hamelech.”
Wonderful claims, but other than that your rebbe was ben achar ben from the Tzemach Tzedek and that he was a son of Reb Shalom Shachna (possibly Altschuler – I don’t know any info about that) the rest is without any basis or proof.
In fact, I took a break and checked Hebrew Wikipedia for information on the Metzudas Dovid – you can find the page under דוד אלטשולר – and despite it explaining his family and ancestors at length there is absolutely no mention of him being a descendant of Dovid Hamelech.
So rather than saying that “the rest is without any basis or proof” I would prefer to say it is another instance of lubavich revisionist fiction. And who believes it? Anyone who cares more about “being on the winning side” than the truth.
At least S”T ym”sh was accepted as being descended from Dovid Hamelech…
