I have been reading two chapters of 《汉天师世家》（卷2、3）. Impression is that it is clearly not a worthwhile canonical texts - it wasn't important in the history of the family until very late in the game, and as written it was not even very useful history, compared to the Buddhist histories written in Chinese - e.g. 《续高僧传》、《国清百录》、《佛祖统纪》etc.
My inclination is to take that out, and replace with another Daoist text. Maybe a commentary of 《周易参同契》
