It's an elaboration of
Katia or
Katya, perhaps inspired by
Tatiana.
Katia is an abbreviated form of
Yekaterina, from Greek Aikaterina, perhaps borrowed from Coptic (St
Katherine was from
Alexandria in Egypt); perhaps from Greek Hekateros "either, one of two"; if related to
Hekate then perhaps from Caria in Western
Anatolia where
Hekate may have been a pre-Indo-European deity later adopted by the Greeks, and where other names perhaps related to
Hekate are recorded. As the meanings of only a few dozen words of the dominant pre-Indo-European language of Western
Anatolia (Hattic) have been deciphered from references in Assyrian and later Hittite documents, the meaning of
Hekate and related names are unknown.
Hekate is just one of several "Greek" deities (other examples are
Aphrodite and
Adonis) whose origins are from outside the Greek and even Indo-European culture.
