My name is Aramis. There are a few meanings to this name from what I have concluded from various research on the internet. I know this is an old thread but no othr site has this information..
1. Aramis- from biblical land of 'Aram' aka Syria. Syrian Christian community Arameans. Last community who speak Aramaic dialect of Jesu. Original Manuscript of some bible books.
2. 3 marketeers character.
3. (Feminine) from Arsemia, Greek commander of Persian army, see the second 300 movie.
4. From Arsames, ancient Persian King.
5. Taken from erebus , ancient vampire, this may be the explanation given in previous comment. Said to be the Lord of darkness,chaos, etc. See: blade 4, or search book of Erebus.
I tend to accept the first meaning more because the other ones seem to be bastardazations.
