She was never sent to school. She married a neighbor at age 15. Her brother Benjamin sent her a spinning wheel as a wedding gift. Her husband, a saddler named Edward Mecom, became physically and possibly mentally ill, and their marriage lasted 38 years.
She had 12 children in her life, but 11 died before she did. One son, Benjamin, disappeared during the Battle of Trenton. Two of their sons went insane. She struggled, and failed, to keep her children out of debtors' prison, the almshouse, and asylums. She took in boarders to earn money. In 1767, along with her daughters Jenny and Polly, she started a small shop to sell caps and bonnets they created using materials sent from London by a friend of her brother Benjamin.
She wrote the story of her life, just 14 pages long, which she called her Book of Ages.
When Benjamin Franklin died in 1790, he left Jane the house in which she lived in his will, and she continued to live there until she died. The house was later demolished to make room for a memorial to Paul Revere.
