I'm working on a historical fiction novel based on a real family's journey as captives marching hundreds of miles midwinter up to Canada. I only have one MC and throughout the book she will mostly be surrounded by her immediate family (2 parents, 4 siblings), and many friends. Discounting other minor characters, there are already too many to keep track of in every event, interaction, scene, discussion, etc. And I find myself having to name every character and what they're doing at the start of every scene, because if I don't, the MC looks like she's forgotten about her family, or is just plain careless about what happens to them (which is furthest from the truth). How do I consistently show the MC's close connection, reliance, and concern for her family -six other characters- without bringing them up repetitively? The stakes in the story are high, so the whereabouts of her family are important, but not something I want to excessively catalog throughout the book.
