Think you might be getting confused as you're getting frustrated (don't worry, we've all been there!)

In Pontus section original strat has:
character_record Laodice, female,

Your strat has got
character_record Laodice, male, command 0, influence 0, management 0, subterfuge 0, age 55, alive, never_a_leader

so a: unless you changed descr_names.txt you shouldn't be using that name for a male.

b: you shouldn't have a male of 16 or over in character record section that's for children and wives only - older males have to be placed on map with an army.

c. from where he is in relative section:
relative Laodice, Pharnaces, Herakles, Spartocus, end
relative Pharnaces, Pythodoris, Dynamis, Gepaepyris, Paerisades, end
relative Herakles, Antonia, Dionysos, Rhescuporis, end
he would also need to be the faction leader for Pontus, which by the way, you don't seem to have one of at the moment.

As you seem to be having problems with family sections - suggest you make a back up of the changes you made - then paste in vanilla family tree and armies for Pontus, just changing x/y coordinates to the ones you want (or any valid location). Do the same for any other faction it complains about below Pontus - get back to a map that loads, then make any alterations you need to families one character at a time. It is painstaking way to do it but advisable even after you think you know what you're doing!!!!
