Names of Slavic deities

Just a very quick question, which may not be answerable for all I know:

1) The Gesta Danorum mentions the deity "Porentius" among the Western
Slavic Wends, late 12th century.

2) The Chronica Slavorum mentions Porenut among the Western Slavic
people, again in the late 12th century.

Does anyone know if there is any linguistic connection between Porenut
and Porentius?
And is there any further connection with the Eastern Slavic deity Perun
(or the Baltic Perkunas?)

Sincerely,
Aydan
