Yes, these two presidents were related, though the relationship was not a very close one.  Franklin Roosevelt was the 5th cousin of Theodore Roosevelt.  Interestingly enough, Franklin Roosevelt was also a 5th cousin of the woman he married, Anna Eleanor Roosevelt (whose maiden name was Roosevelt).

This is not a very close family relationship.  The last ancestor that Theodore Roosevelt and Franklin Roosevelt had in common was a man who lived from 1658 to 1742.  His name was Nicholas Roosevelt.

As you can see, the relationship between the two presidents was not a close blood relationship.  They were each born more than 100 years after the death of their common ancestor.
