EB naming system differs from vanilla.

Search\EB\Data\descr_names.txt for possible names.

In your case it is something like "Cnaevs Romanvs" or if you have more than one Cnaevs you have to add A...K at the first name like in descr_names.txt

Be sure to identify the correct FM by saving the game before doing anything and using "character_reset" to identify him.
