William Rathbone IV  William Rathbone IV (10 June 1757 – 11 February 1809) was a member of the noted Rathbone family of Liverpool, England. He was the son of William Rathbone III and Rachel Rutter, and was a Liverpool ship-owner and merchant, involved in the organisation of American trade with Liverpool. Originally a member of the Society of Friends, he felt compelled to write the "Narrative of Events in Ireland among the Quakers" in 1786 in protest against religious intolerance in the Society, for which he was disowned from the Quakers in 1805. He would never join another religious body, though he occasionally worshipped with local Unitarian congregations. A committed opponent to slavery, Rathbone was a founding member of the Liverpool Committee for the Abolition of the Slave Trade (perhaps another name for the Liverpool branch of the Society for Effecting the Abolition of the Slave Trade founded in 1788, a society originating in London the year before. He married Hannah Mary, (1761–1839) daughter of Richard Reynolds of Bristol and Hannah (née Darby) at the Friends Meeting House, Shrewsbury. They had eight children:   In 1788, Rathbone took a lease on the house and estate of Greenbank, then part of the Toxteth Park property, to serve as a country retreat for his young family, and purchased the freehold of the house in 1809. Rathbone died on 11 February 1809 and was buried at Liverpool Friends' Burial Ground.
