Adrian

sea east of Italy, from Latin Adriaticus, properly Hadriaticus, from town of Atria/Hatria (modern Adria) in Picenum, near Venice, once a seaport but now more than 12 miles inland. The name is perhaps from atra, neuter of atrum "black," hence "the black city;" or else it represents Illyrian adur "water, sea."

in Greek mythology, the daughter of Minos, king of Crete, abducted by Theseus; from Greek Ariadnē, a name of uncertain etymology, but probably Pre-Greek. Beekes points out that "An IE etymology is improbable for a Cretan goddess."
