his return to New South Wales which were that he admits his wrongdoing and promise to be of good behavior. During these periods, Elizabeth oversaw the family estates at Parramatta, Camden, Seven Hills, and Pennant Hills. This included the management of household and business accounts, the employment of convict labor, the supervision of wool washing, baling, and transport, and the selection of rams and breeding to improve the flock. While John expressed his gratitude and admiration for her ability to cope, her irregular and inadequate correspondence were of constant concern. Nonetheless, her contribution was essential to the success of the enterprise and establishing New South Wales as a reliable supplier of quality wool. In England, John used his flair to promote the Australian wool industry while Elizabeth used her organizational ability and application to produce the wool. During her husband's insanity and after his death in 1834, she continued to run the enterprises with great success until her death in 1850. Family From nine pregnancies, seven children survived childhood. Her sons, Edward (1789–1872), James (1793-1794), John (1794-1831), James (1798-1867) and William (1800-1882), made worthy contributions to colonial governance, agriculture, politics and trade. Her eldest daughter Elizabeth (1792-1842) remained unmarried, despite at least two 'offers' declined by her parents. Her younger daughters Mary (Mrs Bowman, b.1795) and Emmeline (b.1808) married into colonial families. Sir Edward Macarthur (1789–1872) married Sarah (née Neil) in 1862, and they died childless. James Macarthur (1798–1867) married Emily (née Stone). They had only one child, daughter Elizabeth (1840-1911). Sir William Macarthur (1800–1882) never married. The bulk of the Macarthur estate, through the brothers William, James and Edward, passed to James' only child, daughter Elizabeth (1840-1911), who in 1867 married Arthur Onslow (1833–1882). In 1892, after Arthur's death, Elizabeth changed the family name to Macarthur-Onslow. She and Arthur had six children, including James Macarthur-Onslow (1867–1946), George Macarthur-Onslow (1875–1931) and Arthur Macarthur-Onslow (1879–1938).
