Re: [tied] Hattic, PIE Myth

Hattic Talipinu (= Hittite Telepinus) is a son of the thunder god Taru.
I've read that Hattic "pinu/binu" means "son".
Thus literally Talipinu is "son of Tali".
Does it mean that Tali is a variant of the name Taru?

Greek mythology offers a number of characters whose names theoretically
could be related to Talipinu/Telepinus:
- Telephos, son of Herakles
and Tlepolemos, another son of Herakles;
- Telphousa, a spring in Boeotia, where Apollon was going to found his
sanctuary
and Delphi, the spring where Apollon did found the sanctuary;
- Delphyne, a dragon, who guarded the latter spring
and also guarded Zeus's sinews in Cilicia (!) during the Typhonia.

Are there true cognates among these names?
