Meaning & History
Probably a more elaborate form of Orestes, which is ultimately derived from Greek όρος (oros) meaning "mountain, hill". It is at least quite unlikely that this is a compound name where the second element is derived from Greek θεος (theos) meaning "god", because then the name would have been spelled as Ὀρεσθεος (Orestheos) in Greek. Orestheus was the name of two characters in Greek mythology, one of them being a king of Arcadia.
