Welcome! There are a few family tree avatars already available:

Andreas Dermokaitis
Vakchos Tzetzis

There are also two that will come of age within 1-2 turns:
Sophronios Komnenos
Ammonathas Kalameteros

And a fifth that is several turns away:
Ioannis Tagaris

If you don't like any of those, we can spawn a Recruitable Bodyguard for you immediately. Let me know which one you'd like.
