Davidovits family may descend from Daithos ( Da-Witsh ) from Lakedaimón who might have like many lakónians been an offspring of Aidés ( Awid ) alias Hadés or Dis called by hebrews Awahayad-Daha,and possibly even of king David who also was named of him : Da-Awid-o-Witsh .
Jews and christians read Yehudah.
