These characters are deceased as of the last or most recent installment in their stories, but the cause of their death is unknown, or not easily defined.
Characters whose cause of death might be easily defined, e.g. murder or killed in action, should be listed in the appropriate sub-category.
Note: Given Turtledove's tendency to write series, and his propensity to set his stories in overlapping time-periods, certain historical characters found in this category or its sub-categories might be deceased in one timeline, but alive in the most recent installment of another. For example, Franklin D. Roosevelt is deceased in the Worldwar timeline, but is still alive in the last volume of the Southern Victory timeline. Additionally, historical persons used in multiple time-lines may have different causes of death from work to work, and so may appear under multiple categories.
This category has the following 6 subcategories, out of 6 total.
