In February 1884 the McMinn sisters moved their school to another property on nearby Buxton Street, which they dubbed "Tormore" for their birthplace in Ireland.
It had been John Whinham's North Adelaide Grammar School, which he relinquished to move to larger premises at the corner of Ward and Jeffcott Streets.
[2] The school was taken over by Ann and Caroline Jacob towards the end of 1897, and the McMinn sisters left Adelaide on 15 December, retiring to Ealing Common, England.
The school moved to new premises at 211 Childers Street in January 1899,[3] with a house for boarders alongside.
In 1907 Caroline Jacob took over the Unley Park Grammar School[4] and ran the two institutions concurrently.
