Note that taking many skills at rank 1 is a common way of exploiting the Insight system to level quickly. As such, it might be better to err on the side of generosity for the length of the skills section.
Lore seems a lot like the Knowledge skills from 3.5 where he skill had a lot of sub groups. The solution used there, listing the skill more than once with a place to list the subgroup, would probably work the best with extra blank lines if they need extra entries.
