Based on the letter frequency analysis I have worked out a possible partial solution. Kind of stuck at the moment. Might have gotten something wrong somewhere.
With the unsolved parts in parenthesis, this is what I've found:
Vex (nous) with smug eyen neuem (ixi) some of git wae death.
eyen: archaic for eyes
neuem: German for anew
git: British for a foolish or worthless person
wae: Scottish for woe or sorrow
nous: French for us
The inconsistency with using both ciphered and unciphered parts and the second half not flowing very well makes me wonder though.
On the other hand, there is the orphan's names.
Ezade: Persian for freedom. (Persia is an archaic name for Iran)
Sithis: British translator Wycliff used the word sithis for seven.
Tarff: Common Scottish name.
Micit: French for siesmicity.
Leaving only German and Iniedia unmatched and the ixi unexplained.
