I looked into how the age/fertility values are defined in regards to the Druedain, and there's some things that don't make sense. Their additional_years_of_fertility value is -20. That means that their marriage_female_fertility_cutoff_age_value ends up being 22, their bride_old_age is 9, and their bride_middle_age is 0. On the other end, their fertility_age_equivalent is age minus 20, letting you appoint a 60-something-year-old wet nurse. There may yet be more bizarre results of the -20, but these are what I found.
