Martha and Daniel were wed on March 3, 1850 in Wyoming. When the butterfly expedition had ended, Martha moved back east with her new husband. On October 25, 1855, they gave birth to Clara in New Jersey.
Before she met Daniel, Martha was a frontierswoman. She found it difficult to ignore her rebellious nature to try to act like a proper 19th century housewife. Her daughter was meek and introspective like her father, but she had her mother's sense of adventure and rebellious nature.
Clara noticed her mother's struggles to suppress her own nature to act like a proper 19th century housewife, particularly while serving dinner when Daniel's brother visited. Coupling her own nature with the knowledge of her mother's struggles, Clara enjoyed the prospect of being an unmarried woman. So, it came to no surprise to Martha when Clara became a schoolteacher. Unmarried women were common in the profession, and she also enjoyed the fact that young minds were open to many new possibilities. They were also truthful and imaginative, like Clara's favorite author, Jules Verne, and like herself.
Daniel died in 1879 and Martha died five years later. They had left Clara a modest amount of money and their house in New Jersey. A year after her mother's death, Clara took a teaching job in Hill Valley, California. She had hoped to find adventure, as well as love, as her parents did on the Oregon Trail. When she met Dr. Emmett Brown, she found both.
