Hello Russell.
I'm at a grave in the Mountain View Cemetery in Piedmont, California, USA.

I have Charles Thorne at rest Jan 23, 1914 with his wife Regina Thorne at rest Oct 14, 1947.

This url goes to a newspaper clipping with the obituary. It says Charles came from Newnham, Gloucestershire, England.

He died at his home 1339 Kansas Street in San Francisco.

It's a great spot under a tree.

Hope this helps.
