The connection between Franklin D. Roosevelt and Theodore Roosevelt is genealogical rather than direct. They were fifth cousins, sharing common ancestors from Dutch and English colonial families in New York. This distant kinship meant they were related by blood but grew up in very different social environments.

The Roosevelt family name had deep roots in early New Amsterdam settlements, and multiple branches emerged over time. Theodore Roosevelt represented the Oyster Bay Roosevelts, while Franklin came from the Hyde Park branch. These family lines converged through shared history yet diverged in temperament and policy focus.
