Step 1 : Introduction to the question "Genealogists have determined that which U.S. president was related to eleven other presidents?"
...Genealogists tracing colonial and New England lineages have found that Franklin D. Roosevelt stood at the center of an extraordinary presidential family web. Through shared ancestors and marital connections, he has been linked to numerous fellow commanders in chief, including Theodore Roosevelt and a long list of earlier presidents. Depending on how distant a cousin one chooses to count, the number can vary, but historians frequently site the figure of eleven. The fact shows how a small circle of families produced many of America’s national leaders.
