This cemetery is not the Griffith Cemetery. It is the Griffiths Cemetery. There is a difference in the two surnames. Look at the road it is on - Griffiths Rd.
Look at the headstones - all Griffiths. Original documents have it as the Griffiths Cemetery but over the years it has indiscriminately been renamed. Other websites have duplicated this error.
This is personal to me as I have two sets of grandparents buried there along with a number of aunts, uncles and cousins.
