Milton Wright, her future husband, was also introduced to her. They married in 1859, and she gave birth to seven children for him between 1861 and 1874. Two of her children died soon after delivery, but the other five lived to maturity. She was a strong-willed woman who wanted her own life outside of marriage, which caused problems for Milton. Katherine Wright was born on April 2, 1838 in Sewickley, Pennsylvania. Her father was a wealthy coal dealer and her mother was from a old Pennsylvania family. She had seven siblings, four brothers and three sisters. When she was only nine years old, her father died in an accident at his coal mine, so she went to live with her older brother William who worked as a police officer in Pittsburgh. He took care of her and her younger sister Mary until their mother died when Katherine was only 14 years old. After her mother's death, she moved in with her oldest brother Milton who was then working as an attorney in Allegheny City. There she met another lawyer named John Edgar Sr. They were both 21 years old at the time and fell in love immediately. However, Milton already had two wives under his belt and didn't want any more, so they decided not to see each other again. A few months later, Milton married Helen Day who had two children from a previous marriage. Then in 1860, he married Katherine herself.
