I notice that Charles William WOOD that you mentioned, died in 1884 in Devon.
A bit of googling revealed as mention that led to a probate for:
On 14 May 1898, Miss Ann Alice PARKER, spinster, of Aberclwyd, Derwen died age 92. Her probate was issued to William Ashbury GREEN £3444, 1s, 3d
And to a sippet in Google Books:
In 1873, the RETURN OF OWNERS OF LAND, Presented to Both Houses of Parliament by Command of Her Majesty, Volume 2, listed:
Anne Alice PARKER , Aberclwyd Derwen
Could this be the right Census, 1871 & 1891:
CENSUS 1871: Aber Clywd, Parish of Derwen and Dyfanedd, Denbighshire

Next door was the address "Lodge", occupied by Thomas HUGHES 42, Slater, b Gwyddelwern, Merionethshire and his wife Ruth and a number of children.
