Samuel Hyde ALLEYN headstone

I've previously written on my ancestor Samuel Hyde ALLEYN and family of Golden, Tipperary:

ALLEYN was also written ALLEYNE, and in a number of records is written ALLEN indicating the names are homophonic. Based on his arrival on the 'Thetis' in 1850 where their name was written ALLEN, he was 47 and so born about 1803, a shepherd, Catholic, and his parents William and Ellen ALLEYN were both deceased.

His arrival record in 1850 stated his health to be 'inferior'. This must have been true as he died 22 Jun 1854. NSW BDM indexes list two entries for the burial of 'Samuel ALLEN':
V1854492 143/1854     ALLEN     SAMUEL     AGE 46            
V18541855 119/1854     ALLEN     SAMUEL     AGE 46            

Margaret Guider has kindly transcribed one of these entries:
'St James Cumberland Samuel Allen 46 years Castlereagh St  buried 25/6/1854 Rev John F Sheridan'

The Parish of St James, Cumberland capture the area that includes St James Station in Sydney, and this includes St Mary's Catholic Cathedral. The age of 46 indicates parents were not recorded, and suggests that he was born about 1808 rather than 1803. Samuel was probably buried at the Devonshire St Cemetery, opened in 1820 and full by 1867. In 1901 the cemetery was resumed to make way for Central Station, and families were given two months to have their ancestors remains removed.

Clearly Samuel ALLEYN's family arranged for him to be moved, as the Rookwood Necropolis (Catholic) indexes show:

Name: Alleyn, Samuel

Date of Death: 1/01/1854   
Interred Date: 17/04/1901

Shortly after William had been re-interred at Rookwood Cemetery, his son Samuel ALLEYN died:

10808/1901       ALLEN       SAMUEL       SAMUEL       MARY       PARRAMATTA   

and he too was buried in the same plot at Rookwood, in the same plot as his father:
Name: Alleyn, Samuel
Date of Death: 8/09/1901
Interred Date: 10/09/1901
Age: 62
Location Section Graves: Mortuary Mortuary 1
Area K
Grave 1850

When in Sydney earlier this year I tried to find this grave with little success (in fact, I searched an empty field!). After returning I wrote to the Catholic Cemeteries Board at Rookwood and they kindly check the plot area again as their records indicated a headstone existed. They also kindly sent me the following photos of the headstone and its precise location:
