Franklin D. Roosevelt and Theodore Roosevelt are indeed related: they share a common ancestor in the 17th-century Dutch settlers of New Amsterdam and are fifth cousins by blood. However, their paths diverged across generations, with Franklin descended from Theodore's younger brother and a distinct branch of the Oyster Bay Roosevelts, while Theodore led the more prominent Rough Rider lineage. This verified relationship explains both the familiar surname and the differences in their political careers and eras.
Shared Roosevelt Ancestry and Family Roots
The connection between Franklin D. Roosevelt and Theodore Roosevelt begins with Claes Maartenszen Van Rosenvelt, who arrived in New Amsterdam around 1649. From this common Dutch ancestor, two main branches emerged: the Oyster Bay Roosevelts, associated with Theodore, and the Hyde Park Roosevelts, linked to Franklin. Both men carry these early colonial roots, but their family trees follow separate directions after the initial settlement.
The Oyster Bay and Hyde Park Lines
Theodore Roosevelt belonged to the Oyster Bay branch, a more politically visible group in New York and national affairs. Franklin D. Roosevelt descended from the Hyde Park branch, which remained prominent but operated more locally in Dutchess County. Despite geographic and social differences, both families retained close ties through shared history and property interests in New York state.
Fifth-Cousin Relationship
Franklin and Theodore were fifth cousins, meaning they shared great-great-great-grandparents. Their most immediate common link is through Roosevelt patriarchs who lived in the 1700s, with converging family lines that meet in the mid-19th century. This makes Franklin a distant relative of Theodore, but not a direct descendant in the familial succession many assume.
Theodore Roosevelt’s Family Tree
Theodore Roosevelt was born into the Oyster Bay Roosevelts, a family known for public service, land ownership, and civic leadership. His father, Theodore Roosevelt Sr., was a prominent philanthropist in New York, while his mother, Martha Bulloch Roosevelt, came from a respected Georgia family. This upbringing shaped his energetic, reform-oriented approach to politics.
Key Figures in Theodore’s Lineage
- Theodore Roosevelt I and Martha Bulloch, parents of the Rough Rider and future president.
- Cornelius Van Schaack Roosevelt, Theodore’s paternal grandfather, a businessman and community leader.
- Nicholas Roosevelt, an early inventor and contributor to the family’s industrial interests.
Franklin D. Roosevelt’s Family Background
Franklin Delano Roosevelt was born into the Hyde Park branch of the family, led by James Roosevelt I and his wife, Rebecca B. Howland Roosevelt. The Hyde Park Roosevelts were closely tied to Dutchess County society, with strong connections to law, land, and local governance. This background emphasized stability, property, and measured public involvement.
Core Hyde Park Ancestors
- James Roosevelt I, Franklin’s father, a businessman and community figure.
- Rebecca B. Howland Roosevelt, Franklin’s mother, influential in local charitable circles.
- Isaac Roosevelt, an early family member linked to the banking and shipping trades.
Political Careers and Public Perception
Theodore Roosevelt became known for his energetic reforms, trust-busting, and foreign policy assertiveness as the 26th president, while Franklin D. Roosevelt led the nation through the Great Depression and World War II as the 32nd president. Their approaches differed in style and scope, shaped by their eras rather than by direct mentorship, although Franklin acknowledged his cousin’s influence on progressive thought.

Family Connections and Misconceptions
Many assume Franklin was directly descended from Theodore, but this is not accurate. Franklin’s father, James Roosevelt I, was a cousin, not a son, of Theodore Roosevelt. Their relationship was one of distant cousins who occasionally interacted within New York high society, but their political careers unfolded in largely separate spheres.
Clarifying Common Myths
- They were not father and son or direct ancestor-descendant.
- They shared a surname through common colonial ancestry, not direct lineage.
- Their political similarities were largely coincidental, shaped by the Progressive Era rather than family instruction.
Conclusion: Related but Distinct Legacies
Franklin D. Roosevelt and Theodore Roosevelt are fifth cousins connected through the early Dutch settlers of New Amsterdam. Their shared surname reflects this family relationship, but their political careers, policy priorities, and historical contexts were shaped by very different times and personal experiences. Understanding their connection clarifies their relationship without overstating its direct influence on their presidencies.
