"raj" and "rosh" - any etymological connection?

“raj”, in Sanskrit and various other languages, means royalty, leader, kingdom, etc. It also appears to be an honorific in some Asian languages.

“Rosh” in Hebrew, means “head” as “primary” or “first” as in Rosh Hashanah (the ‘head of the year, New Year’s Day) or Rosh Hamemshalah (Head of Government). It’s also very closely related to the Arabic “Ras” in both sound and meaning.

And there is “roi”, French, for “king” or “royalty”, which was derived and descended from the Latin ‘rex”.

My question – is there an etymological connection between them? It seems to me that the similar in sound and meeting strongly suggests it, but I haven’t found anything that agrees with me. Possible?
