How to Actually Map Out the Greek Divine Family Tree Without Losing Your Mind
The Greek gods are not a clean lineage. If you look at any family tree diagram online, it will lie to you in at least three places. The reason is that the ancient sources were not consistent with each other, and later writers made up their own versions on the fly. I spent years tracking down who parented whom across Hesiod, the Homeric Hymns, Ovid, Pseudo-Apollodorus, and fragments from pre-Socratic poets. The result was a document that most people find useful once they stop expecting it to be simple. Start with the very first generation. Chaos emerges, then Gaia (Earth), Tartarus, Eros, and Erebus plus Nyx from Chaos. Gaia births Uranus (Sky) parthenogenetically. Then Gaia and Uranus produce the Titans, the Cyclopes, and the Hecatoncheires. This part is consistent across nearly every source. Where things fall apart is immediately after. Cronus overthrows Uranus, marries his sister Rhea, and eats his first five children because of a prophecy. Zeus escapes, forces Cronus to regurgitate them, and the Titanomachy follows. That is the backbone. The backbone is not controversial. The branches are where anyone doing serious work runs into problems.
The Olympian Core Generation
Zeus and his siblings are the Olympians by default: Hera, Poseidon, Hades, Demeter, Hestia. Zeus then fathers another massive cluster through multiple partners. The common ones matter for the tree: Hera produces Hephaestus parthenogenetically in most accounts, though some sources say Hemera or Ares. Athena is born from Zeus's head after he swallows Metis. Apollo and Artemis come from Leto. Hermes from Maia. Dionysus from Semele and later reborn from Zeus's thigh. Persephone from Demeter and Zeus. These pairings are stable enough to trust. The secondary Olympians are the ones that trip people up. Hebe, Iris, the Graces, the Horae, the Muses, the Charites, the Moirai. Some are children of Zeus alone, some with various mothers. The Muses come from Mnemosyne and Zeus, nine of them, which is standard. The Horae are daughters of Zeus and Themis in Hesiod but have alternate parentages in different regional traditions.
Titans and Their Progeny
The Titan generation matters because they seed almost every divine bloodline that crosses into the Olympian era. Cronus and Rhea: the six Olympians plus some minor figures. Oceanus and Tethys: the Oceanids and the river gods. Hyperion and Theia: Helios, Selene, Eos. Coeus and Phoebe: Leto and Asteria, which makes them grandparents to Apollo and Artemis. This lineage detail is important because it means Apollo and Artemis are direct descendants of both the Titans and later Olympians. That is not a trick. It just happens in the mythography. Prometheus, Epimetheus, and Atlas are Titans too. Atlas fathered the Hyades and Pleiades with multiple mothers. Atlas's daughters marry various heroes and gods. The Hyades are flood nymphs associated with rain. The Pleiades are star nymphs. Both are relevant because they connect the Titan line into the heroic age through marriage.

How I Actually Built This
I did not start by drawing lines. I started by extracting every genealogical mention from the primary sources into a spreadsheet. Each row had a child, a parent, a source citation, and a confidence tag. The confidence tags mattered more than the lines. A parentage from Hesiod's Theogony with no competing account gets a higher mark than one from a Roman poet writing three centuries later who changed the story to suit a narrative agenda. From there, I grouped by generation rather than by relationship type. That exposed contradictions immediately. For example, Hesiod says Aphrodite is born from Uranus's severed genitals. Later traditions make her a daughter of Zeus and Dione, which appears in the Iliad. Both exist in the canonical corpus. The workaround I used was to include both versions in the tree with clear source tags instead of picking one. The tree became larger but accurate. Edge case: the lineage of Orphic theogony completely restructures the early generations. Phanes replaces Chaos as the first deity. Chronos and Ananke create Orphic Eggs. If you try to merge Orphic material into a standard Hesiodic tree without separating them, the result is nonsense. I kept the Orphic lineage as a parallel branch. That cut confusion for readers by a lot, though it doubled the document size initially.
Counter-Intuitive Points Beginners Miss
One major misconception is that Hades is not an Olympian. Technically he is a brother of Zeus and a god of the cosmic order, but he does not reside on Olympus. Most standard lists include him among the twelve due to his brotherhood and dominion. Some strict definitions exclude him. Neither interpretation is wrong, but picking one without noting the ambiguity causes arguments that go nowhere. Another issue involves the concept of autochthonous beings. Some figures emerge from the earth without parents. Erigone, for instance, is sometimes autochthonous. These entries break standard parent-child links. The fix is to allow null parents and tag those nodes differently. It preserves accuracy without forcing false connections.
Divine Marriages and the Heroic Age
Once you get past the Olympians, the tree expands through divine-human unions. These produce demigods and legendary founders. Heracles from Zeus and Alcmene. Perseus from Zeus and Danae. Ajax from Telamon, which removes him from divine parentage entirely except through his ancestor Zeus. These lineages matter for understanding the full scope of Greek genealogy. The Trojan War generation connects through multiple routes. Peleus and Thetis produce Achilles. Their grandson Neoptolemus appears in later traditions. Agamemnon and Menelaus descend from Atreus, who descends from Pelops, who descends from Tantalus, who is sometimes a son of Zeus. Each generation adds another branch that intersects with others through marriage or rivalry.
Practical Limitations
This guide does not solve every contradiction. Regional cults maintained different versions. A genealogy valid in Athens might differ from one in Sparta or Argos. If you need academic precision, you must specify the tradition you are using. No single tree satisfies all regional variants simultaneously. The document also does not cover every minor deity. There are thousands of nymphs, river gods, and local spirits whose parentage is mentioned in passing by a single author or not at all. Including them would make the tree unusable. The focus remains on the major divine families and their direct descendants.
Accessing the Full Tree

It tags every parentage with its source and notes where contradictions exist. The format separates conflicting accounts instead of hiding them. You can download it through the provided link below.
