Before I start I have to clear up some etymological problems;

No, Era and Hera are not connected. Era comes from Latin aere. Hera is probably related to ἥρως “hero” &lt; PIE *ser “to watch over, to protect”.

Yes, Tomarus is the original name for Tomor, yet still shows traits of words borrowd in Albanian after the Roman Era. But it doesn’t deny it being a regional epithet. It just doesn’t connect him with the Sky Father.

E Bukura E Dheut is clearly a mixed character though. The original, if we may call her that way, is presumed to be remnant of an underworld deity connected to spring a la Persephone. But she also plays the role of the Sun Maiden, equivalent of Helen of Troy in Greek mythology, in our folktales of Horse Twins, equivalent the Dioscuri in Greek mythology. And then there is this character which is the wife of Tomorr.
