Genealogy: Roman Pantheon
The genealogy of the Roman deities is basically the same as those of the Greek deities, except that many of their names have changed to Roman or Latin names. For example, Zeus, Poseidon, Hera and Athena have been changed to their Latin forms as Jupiter (or Jove), Neptune, Juno and Minerva.
I should point out that most of the Titans retained their Greek names.
