Family Tree of Tuatha De Danann

Hopefully yall saw my post earlier about how hard it is to make a proper family tree for the Irish Pantheon. As a result, the layout here is a little different than usual and the names I’m using are the more common spellings for all the characters but they are by no means universal (as usual)

This is very long so it’s going under a cut. I will preface this by saying that Danu is more commonly seen as the Mother-Goddess of the Tuatha De Danann (hence their name), and so is usually The Dagda’s mother and/or wife instead of his daughter, but I had to include all versions just to cover my bases

Also this is not a complete list, it’s just all the info I’ve gathered, I’m sure there’s a lot more you can find out there

Danu's sons: Dagda, Dian Cecht, Nuada, Lir, Ogma (all have different fathers)

Indui’s son: Neit (fomorian, King of Tuatha De, favoured his brethren so was disliked, also The Dagda’s Uncle)

TW below for suicide mention

Though most people know Niamh as Manannan’s daughter, in the oldest text she was human, daughter of Aengus Tirech, King of Munster. She spent 6 weeks with the Fianna before her father arrived in pursuit of her. She then killed herself for fear of him, alongside thirty other women

It’s possible there are two different Niamh’s, as the poem in which Niamh is a Fairy Woman may have been based on lost traditional material
