This family consisted of Morley Unwin (a clergyman), his wife Mary, and his son (William) and daughter (Susannah).
All went serenely until in July 1767 Morley Unwin was thrown from his horse and killed.
It can scarcely be doubted that this second attack interrupted the contemplated marriage of Cowper with Mary Unwin, although Southey could find no evidence of the circumstance and Newton was not informed of it.
New friends were wanted, for in 1792 Mrs Unwin had a paralytic stroke, and henceforth she was a hopeless invalid.
Johnson took Cowper and Mary Unwin to North Tuddenham, thence to Mundesley, then to Dunham Lodge, near Swaffham, and finally in October 1796 they moved to East Dereham.
