Send a message to the person who requested a photo of the grave monument of George Drever with the following comment:
I descend from Sinclair-Drever family originating in Orkney. Trying to find any reference of the double-barrelled surname in Orkney from that time (mid-late 1800's). One of the names on this gravestone is Jemima Sinclair Drever. My Family has been in South Africa since 1906.
