December 1986 – J.Daryll Evans: In his book The Churchyard Yews of Gwent recorded a girth of 651cm (21′ 4½”) at 1m.
March 1998 – Tim Hills: A tall yew with a fine internal stem filling part of its hollow. It grows ESE of the church. Girth recorded in 2000 of 23′ 3” (709cm) at 3′ and 22′ 0” (671cm) at 5′.
2017 – Peter Norton: The large female yew grows close to the southeast corner of the church. It has a large flared root which hindered measurement below the nails that somebody has hammered into the tree at a height of 4′ 6”. I used these nails to record a girth of 22′ 4” (681cm).
