For Julius I have Ida? I could see her as Climber (though not her choice), or Good on Paper.  Probably has a decent dowry for MC, as family biz is going well. Starting from end of July/August she's got a few friends in UC who are really pushing to set her up with someone in UC, doing all the intros/matchmaking. xD Her older brother might be pushing Ida that direction also. Ida, on the other hand, really doesn't think she likes most men. She plans to go to Flint Institute and do advanced research work, and assumes a suitor probably won't like this. 
 


For Araminta I have a newbie coming up Cassian of course! He's destined for a doom-spiral endgame with another, but there's plenty of time for him to make his rounds before that! Good for seeking public future I guess? 
Otherwise Thomas Harvey for the chaos of a handsome WC who's very much not what Julius wants for his sis.
