I want to publish a tarot deck based on the life of a famous dead person. How can I do this legally?

I want to publish a tarot deck and it’s corresponding instructional book based on the life of a famous dead person. Each tarot card would include illustrations of that famous person and their life history as it corresponds to the symbolism of the tarot. However, the illustrations would in no way identify the person or the people they knew when they were alive. However the written interpretations of the cards could lead to their identity. Any information used to discuss this famous dead person would be taken from the public record (newspapers, bios). How can I avoid breaking copyright law?
