The first women distinct from apes - wife of A'ad-Dam-Ma living in Marayo region,founder of Dammiawaadi dynasty of kings - is called in the Byble by the name HhWh - meaning Life or Living - read by jews nowadays as Khayah and by latins or greeks as Hewa or Eva.
A male version of her name could be HhW ( "Khay " ) - corresponding to Ek-ha-Wa equal to hungarian Waek - that was given to the Inga son of Sharrawarra'a living approximately between 969 and 1038 according to greeks counting from 858 b.c. that corresponds to 424 and 492 of Seleykid aera and to real 111 and 180 after incarnation . He ruled beyond river Danube at rugi nation of the great plain possibly descending and coming from town of A-Wag-Ra-Zar of Ganda and was therefore called either Stepp-K'han - ,husband of Gisela and son of Geysa son of Bela son of Colomann son of Athyla,father of more sons - or on their native tribal language of Ugra either Feleteus ( Fi-Élete ) or Feva ( Fi-Éva ) ,husband of Gisa, in the meaning : Male Eve that is Male Life .
As he was killed or just defeated by Odovakar ( Otakar ) rugians remained without king and were subjugated by intrusive longobards . Some time leater longobards likely together with the remainder of rug nation moved towards the region called Feld in their language that might have been in Pannonia and in Nóreia somewhere .
So I think the origin of some Feld families is related to these events and their ancestors took the name of their new home that in some measure coincided with the one of their late king they might also have had descended from.
