Robert Ibbotson (1839-1896), an ivory dealer and cutter, was the son of George Ibbotson and his wife, Eliza née Driver.  George Ibbotson was born in Bradfield and by 1841 was working as an ivory cutter in Charles Street (the Driver family cut ivory in the same street).  In 1861, George employed two boys in Coalpit Lane.  In 1862, his address was Beehive Works, Duke Street.  He died on 12 August 1869 at Bole Hill, Crookes, leaving under £1,500.  He was buried in the General Cemetery.  In the 1860s, Robert launched a career as an ivory merchant at Livingstone Works, Holly Street, with his brother, John Driver Ibbotson.  This was dissolved in 1872.   In 1880, ‘Great Sale of African and White Ivory’ was advertised at Livingstone Works, comprising 13,000 dozens of African and white ivory handles; 300 dozens of ivory razor scales; 800 gross ivory pen knife scales (Sheffield Independent, 28 February 1880).  Robert Ibbotson, 31 Ashdell Road, died on 30 October 1896, aged 57.  His burial (unconsecrated) was in the General Cemetery (Sheffield Daily Telegraph, 3 November 1896).  Two daughters and a son died as infants.  He left £19,577.  His sons, Robert Jun. and Livingstone, continued the business after his father’s death.  John Driver Ibbotson died on 17 February 1910, aged 73.  By 1919 only two descendants of George and Eliza were dealing in ivory in West Street:  Omar Pasha Ibbotson (1854-1920) and his son, Omar Pasha Jun.  The former died on 30 July 1920, leaving £11,074.
