Editing family trees

I'm not sure if this has been asked before, but what is the format for editing family trees? I'm confused by the amount of space inbetween names and so forth...

Thanks in advance.

Try to search this forum,subject was discussed here few months ago but I can't remember what was the final conclusion.Personally I would copy existing family tree from another faction and replace the names.Remember to keep the same spaces btween sons and daughters otherwise campaign might not load.
