There is no record of a plaque at Pembroke Lodge. "There is, however, an ornamental bird bath in the grounds bearing an inscription to the effect that it was presented by the Russell family to commemorate many happy years spent there." There is already a plaque at 37 Chesham Place in London "erected by the London County Council in 1911. It is not the usual practice of the Council to erect more than one plaque to one individual ... I understand the Department of the Environment is preparing a plaque stating the connection between Pembroke Lodge and Lord John Russell and Bertrand Russell to be erected inside the house in a position where it can be seen by the public."

Note: The LCC plaque was still attached to Chesham Place in 2012. It reads: "Lord John Russell 1st Earl Russell 1792–1878 Twice Prime Minister Lived Here." I did not see the Dept. of Environment plaque at Pembroke Lodge. S. Turcon
