Firstly, we don't know
any Indo-European root words - we can guess at the possible shape of some of them by comparing similar words across the various languages, but we don't actually know what any of them sounded like.
According to my research, Iran is a modern version of Aryan, referring to the ancestry the Iranians lay claim to. Both of these come from the Sanskrit term arya, which does mean noble. The name Aryana
comes from this, but while its meaning may be derived from arya, its given meaning is "from the land of the Aryans", ie "from Iran".
So yes, I'd say Aryana
(which could also be spelled Ariana
) and the Ariadne Ariana
are just coincidental forms.

Most names which mean "noble" in the BtN database are from the Germanic root word adal
. Also, Adara
means "noble" in Hebrew and Alina
means "noble" in Arabic.Hope
