Delanos

Delanos is a surname of Dutch origin that has appeared in American historical records since colonial times. The name is most closely associated with a family line that rose to prominence in the 19th century through mercantile activity and connections to broader commercial networks in New York and in transpacific trade.

A notable branch of the Delano family was led by Warren Delano Jr. (c. 1809–1893), a merchant whose business interests and wealth funded later generations. His daughter, Sara Delano Roosevelt (1854–1941), became a prominent social figure and the mother of Franklin D. Roosevelt, the 32nd president of the United States. The Roosevelt connection is often highlighted in discussions of the Delano surname because Franklin Delano Roosevelt carried Delano as his middle name, reflecting the maternal family lineage.

In addition to these connections, the Delano name appears in varied colonial and later American contexts, with bearers who participated in agriculture, business, and public life. While the Delanos are not associated with a single enduring institution, the family is frequently noted in genealogical and historical accounts for its role in the networks of 19th- and early 20th-century American commerce and social circles.

Today, Delanos are part of broader discussions of American family histories that include the Delano lineage as a link to the Roosevelt family and to the broader story of Dutch-origin families shaping early and modern American society.
