*is happy that the Elvish pronounciation of vowels is almost identical to the German one*
I think
Eönwë is correct with eh-
on-weh. The 'e' needs to be the way
Legate said, but 'eh' is simpler and close enough. The 'w' definitely has to be pronounced as an English 'w' and not like a 'v'.
And now, for a challenge...

ee-
bree-nee-theel-pah-
thah-neh-zehl?
And for completeness' sake...
mahk-ahl-
ow-reh
(the first 'th' in
Ibri's name should be soft, and the 'r's should be trilled)
