Glad to see someone is recording, locally.
Potter /Anderson are my ancestors and the gravestone has obviously deteriorated in the last 30 years.
It should read:
"In memory of JOHN Potter, who died 1st October 1869, aged 45 years, and of four children who died in infancy, and Elizabeth Anderson, wife of the above died 1888."
The Potters are from Uphall and the Andersons from Kirkliston.
The very large headstone I have assumed was put up by the estate, as he was a forester and died of an accident on the Hopetoun Estate
There is a superb,fully recorded gravestone site for St Nicholas Church Uphall, on the web, for any others interested.
Hope this helps
