Hi Annelaine ...
... thanks for asking. I don't have the grave number but I was told it is near the line of trees and wall between the old and the new parts. There are a couple of gaps in that area. The name is Lewis Thomas (born 1821, died 1899), I don't know if his wife Catherine is there or not, she died in 1915.
... I did find Lewis's father there, William Thomas (1794-1876), along with his wife Elizabeth (1799-1865), a daughter Anne (1840-1915) and a son-in-law Owen Williams (1823-1907).
Where can I view the book?
Regards
Dave
