Ἔφρων ἢ Ἐφραία → Ephron or Ephraia

[neoslash]

Sorry for the caps, but that's just how the original text is written.

In the title there are two (or the same?) place names, Efron and Efraea, taken from the ancient Madaba map (Jordan) as they appear on it.
I would like to know what the 'H' could mean or imply in this case, when it's placed between two names and without any punctuation/vocalization. I am looking for all possible options.

Thanks!

The Greek letter eta (H) is also the word for "or."  So your phrase involves two names for the same place:  "Ephron or Ephraia."

Is that the only possible translation?

Yes.  You can of course vary the spelling of the names, depending on what your audience is used to.  My spelling is Hellenized.  Yours is partially Latinized, partially phonetic.  ΒΤW, "Ephraia" simply means "land of Ephron" (Ἐφραία γῆ).
