****John Armstrong passed away in Mackay and is most likely interred there as he does not appear on Toowong Cemetery records.

****I could not locate Thelma Fagg (nee Warren) on Cemetery records so her name may be on the headstone in memory only. Her date of passing was taken from Queensland BDM records.

***Lewis John Warren was referred to as Jack in his funeral notice so the separate little headstone is his.
