Shown here are pages from Wulfsohn's book. The first shows the two Boer monuments. Fauconnier's name is on the left in line 7 of the list of names. The second is Wulfsohn's summary of the number of casualties at Nooitgedacht.
The book includes a list of the Boers from Rustenberg who were killed in action or who died while on commando. Fauconnier's names is not on the list, so presumably he was not from Rustenberg.
