Hi
Yes sorry about that .I went with the transcription on Find a grave
https://www.findagrave.com/memorial/150138326/mary-margaret-hughesHowever they are all on the same gravestone and her age can't be right because son Clifford is given as born 1839 .Trouble is ,the first digit of her age at death is so worn it's difficult to tell.
She *6 years old in 1866.
So given son Clifford born 1839 her year of birth has to be 1820,1810 ,1800.
Looking at another data set Sydney, Australia, Cemetery Headstone Transcriptions, 1837-2003 on Ancestry it says 56.
Clifford Thomas Henry was baptised 26 Dec 1841 birth date May 25th Liverpool St Luke Sydney so that doesn't quite match up either. (Clifford's entrance to Darlinghurst jail in July 1860 also says age 20 so born 1840).
