Why did Cornelius Vanderbilt Mary his cousin?

Answer 1

Cornelius Vanderbilt married his cousin, Sophia Johnson, primarily due to family ties and societal norms of the time, which often encouraged such unions to strengthen familial connections and consolidate wealth. Their marriage in 1813 was also likely influenced by the close-knit nature of their social circles and the limited options available for suitable partners. Additionally, marrying within the family was common in the 19th century, particularly among the affluent, to maintain control over resources and ensure loyalty within the family.
