Can't be sister of people who live 200 years after her. big mistake
wife, Yitzhak, Bat Maharsha Spitzkopf
You are right! there are MANY mistakes in the Geni trees, some of them not based on real documentation. I, for instance, have an undocumented "statement" by my great grandfather published in a book by the family after his death, that he is the 8th generation of the Maharshah. Being a very religious man, he supposedly had an oral family tradition about it, as well that he was the 5th generation of Alexander Ziskind of Grodno. But who knows?
