How on Earth Do you Add Characters to your family tree????

[Makanyane]

OK that sounds like Brutii family tree, its quite handy when working with family tree to COPY and paste copy of relevant bit into word or notepad doc so you can print relevant bit and write notes on print, so I'd make print and mark up relative section as below, taking dates of birth from army section and character record section, so you'd have on your print out:

character_record		Cassius Brutus, 	male, command 0, influence 0, management 0, subterfuge 0, age 14, alive, never_a_leader
character_record		Titus Brutus, 	male, command 0, influence 0, management 0, subterfuge 0, age 10, alive, never_a_leader
character_record		Cornelius Brutus, 	male, command 0, influence 0, management 0, subterfuge 0, age 7, alive, never_a_leader
character_record		Oppius Brutus, 	male, command 0, influence 0, management 0, subterfuge 0, age 3, alive, never_a_leader
character_record		Galla, 	female, command 0, influence 0, management 0, subterfuge 0, age 50, alive, never_a_leader
character_record		Hostia, 	female, command 0, influence 0, management 0, subterfuge 0, age 30, alive, never_a_leader
character_record		Lucilla, 	female, command 0, influence 0, management 0, subterfuge 0, age 28, alive, never_a_leader
character_record		Paulina, 	female, command 0, influence 0, management 0, subterfuge 0, age 12, alive, never_a_leader

relative 	Tiberius Brutus(52), 	Galla(50),		Aulus Brutus(34)1stchild,	Amulius Brutus(31)2nd child,	Vibius Brutus(30)3rd child,	end
relative 	Aulus Brutus(34), 	Hostia(30),		Paulina(12)1st,	Titus Brutus(10)2nd,	Oppius Brutus(3)3rd,	end
relative 	Amulius Brutus(31), 	Lucilla(28),		Cassius Brutus(14)1st,	Cornelius Brutus(7)2nd,	end

Got fed-up with marking the notes in red but you get the idea, thats just for your reference so you can visualise whats going on.
From your notes and referring back to my earlier post you should be able to see that Tiberius and Vibius both have space to have one more child, Amulius can have another 2.
Your example was that you wanted to give Amulius a son aged 9, he can have that but the 9 year old needs to be listed between Cassius whos 14 and Cornelius whos 7. You can't actually call him Tiberius in this example as that name is already in use for another leader, look up the Brutii section in descr_names.txt and select new unused name. Herius would be a valid name, you would add him by adding the parts in blue:

character_record		Cassius Brutus, 	male, command 0, influence 0, management 0, subterfuge 0, age 14, alive, never_a_leader
character_record		Titus Brutus, 	male, command 0, influence 0, management 0, subterfuge 0, age 10, alive, never_a_leader
character_record		Cornelius Brutus, 	male, command 0, influence 0, management 0, subterfuge 0, age 7, alive, never_a_leader
character_record		Oppius Brutus, 	male, command 0, influence 0, management 0, subterfuge 0, age 3, alive, never_a_leader
character_record		Galla, 	female, command 0, influence 0, management 0, subterfuge 0, age 50, alive, never_a_leader
character_record		Hostia, 	female, command 0, influence 0, management 0, subterfuge 0, age 30, alive, never_a_leader
character_record		Lucilla, 	female, command 0, influence 0, management 0, subterfuge 0, age 28, alive, never_a_leader
character_record		Paulina, 	female, command 0, influence 0, management 0, subterfuge 0, age 12, alive, never_a_leader
character_record		Herius Brutus, 	male, command 0, influence 0, management 0, subterfuge 0, age 9, alive, never_a_leader

relative 	Tiberius Brutus, 	Galla,		Aulus Brutus,	Amulius Brutus,	Vibius Brutus,	end
relative 	Aulus Brutus, 	Hostia,		Paulina,	Titus Brutus,	Oppius Brutus,	end
relative 	Amulius Brutus, 	Lucilla,		Cassius Brutus,    Herius  Brutus,   Cornelius Brutus,	end

EDIT: just saw your other post, yes you can change the ages but you have to remember to obey the dad is 16 years older than any son rule, and keep them in correct age order, you also can't have twins!
