I have been studying the gods and goddesses' famly tree and here is what i have so far:

Ra/Re emerged from Nun, the reging waters of chaos. from Ra/Re came Shu and Tefnut. From Shu and Tefnut came Nut and Geb. From Nut and Geb came Isis, Osiris, Nephthys, and Seth/Set. From Isis and Osiris came Horus and from Nephthys and Osiris came (my personal favorite) Anubis. From Horus came Amset, Hapi, Duametef, and Khebehsenuf. Oh yes. From Ra/Re and Nut came Hathor.

And thats all I know so far. If you have any more info please tell me.

There are many problem with figuring out relationships in egyptology.

Ra(Sokar)/Sekhet are parents of Geb
Shu/Tephnuit are parents of Nuit... Nuit Might be Nepthys(?)
Geb and Nuit have 3 sons - Osiris, Horus(over the horizon), Seth

The Horus line is very tricky because they are all called Horus after Horus over the Horizon.

Osiris marries Isis(not his sister)(translation error of daughter vs. daughter in law), Seth marries Merneith(Neith)

Nepthys is described as a second wife of Seth... who never had sex with him.... she could also be mom coming to live with him after Geb dies (it is not clear)

Osiris and Nepthys have a son(Amset) (previous incorrectly guessed Anubis). Seth kills Osiris for sleeping with Nepthys (unclear if this is mom, or his second wife).

Isis remarries Horus Over the Horizon. They have 3 sons, plus one adopted son.
Amset(human) - marries Ta bitjet(Qa hedjet)
Hapi(Babboon) - unknown wife
Tuamatef(jackal) marries Buto
Quebsenuf(falcon) - marries (Nekhebet)

On the Seth side:
Seth - married to Merneith
Den(Sobek)(Crododile)
Den marries Hathor (Heret-Hor)
Buto(Wadjet) marries Tuamatef(Anubis)
Buto has a daughter nekhebet, and a second child(Bastet or Nefertum)
Bastet marries Semerket(Nefertum)
They have a son Qaa(Maahes)
Huni seems to be the next pharoah
