Patrick was mentioned in an article I found in The Sydney Morning Herald that was published on Monday 27 Sept 1869.
This article explained how a man named Richard Guilfoyle was killed during a rock fall at one of the Pyrmont quarries that Patrick Fleming was leasing, with Richard Dunn. The article describes the location of the quarry as being near the Blackwattle Swamp Bridge. Based on my analysis of some old maps, I think that the quarry where he worked may have been close to where the quarry known as Purgatory was located, near the Blackwattle Swamp Bridge.
Patrick FLEMING died on 12 October 1880 at Little Abercrombie St, Sydney (Chippendale) and was buried at the Catholic Cemetery in Petersham although this cemetery has since been closed.
I hope he's in Paradise now.
