I don't think any unique troops will be in, it would be too complex. Every vassal will provide their lord an army based upon the composition in their province.
Tatars/Turks will give more horse archers/light cav, the welsh longbows, etc.
In any case, as all Dynasties are playable, there simply wouldn't be enough information as to what tiny little dynasty would have an elite unite. This is not Age of Kings.
Furthermore- As each Vassal will be run by a separate AI, I would expect the quality of troops raised, as well as composition, to be highly variable. Some will concentrate on military techs, others will concentrate upon economics, others defence etc. Maybe the Welsh dynasties will start out with some additional archer techs.
