In 1802 Lowther's heir, William Lowther, 1st Earl of Lonsdale, paid the 4,000 pounds owed to Wordsworth's father through Lowther's failure to pay his aide. It was this repayment that afforded Wordsworth the financial means to marry. On 4 October, following his visit with Dorothy to France to arrange matters with Annette, Wordsworth married his childhood friend Mary Hutchinson. Dorothy continued to live with the couple and grew close to Mary. The following year Mary gave birth to the first of five children, three of whom predeceased her and William:
- John Wordsworth (18 June 1803 – 1875). Married four times:
