So, there was Jakov, Akiva, Zvi and is'hak (יעקב,עקיבא, צבי ויצחק). I type this in Hebrew on purpose cause that the mane pointer to the names in family. 4 children from the second/third wife of Abraham (Hearschel is translated automatically to a deer - Zvi). I Have a theory says the first wife gave birth on some year after 1850 to an older brother named... S a m u e l (שמואל)
Such a son of him named for his ancestors... A b r a h a m - H i r s c h (אברהם-צבי), and that I can corroborate across all the stories of h i s son (my grandfather RIP) whom I called... S a b a (Gran'pa) S h m u e l (and, by the way, my dad RIP was also called Avri - Abraham Chesler)....
Let's discuss about this ! !
