Step 1 : Introduction to the question "How were Theodore Roosevelt and Franklin D. Roosevelt related?"
...Theodore Roosevelt and Franklin D. Roosevelt were fifth cousins, both descending from a common ancestor in the early Roosevelt family of New York. Although their connection was fairly distant, the shared surname often leads to the mistaken belief that they were more closely related. The family ties became even more intertwined when Franklin married Eleanor Roosevelt, who was Theodore Roosevelt’s niece. Despite the distant blood relationship, both men rose to the presidency—Theodore from 1901 to 1909 and Franklin from 1933 to 1945.
