Aedui Campaign - Caturige FM

Hello everyone
Just wanted to share the following....
Something I found very interesting in my Aedui campaign involves a certain family member that is a Caturige. The description of the trait states that he is a savage (more so than the rest of my gaul barbarian FMs) and will have trouble improving his political skills and the way other people see him. And this is a promise kept. Even though this dude has the Romaereitha trait (the third FM to have the privilege) giving him a +1 Influence bonus as well as a couple of other traits for a total of +3 and no negative traits, he has no wreaths in his influence line and of course no positive public order effects, when he is in a city. Has anyone else seen this? Are there other tribes like the Caturiges to which FMs can belong to? I have completed the Sweboz campaign but do not recall anything similar...
