Nachmann family amay descend from An-Nak-Ham-Ma-Wa-Ha-ya known by americans as Huemán ( Ha-wa-ya-ma-an ) who led some of the toltecas about 565 b.c. back to the Holy Land after the exile in Babele.
He together with Spitama Zerdusht is suspected with the final redaction of the so called Byble written in the language used in Babele by sons of Ak-Eya-Sha there,while the five books of "Mosheh" (MShH) may have been written by king "Manassheh" (M-N-ShH ) during his exile in the same Babele using the same language about 100 years before.
Jews and christians call them Nekhemyah - that is Haman - Eezrah.
