This is Montague Summer's headstone. I really like the font of of the quote and was wondering if someone could help identify it. I don't know if it is just particular to this stone or it was a commonly used font for head stones in the early to mid 1900s.

English Engravers Roman  Suggeriti da elzadra 
Californian  Suggeriti da zules 

Not exact, because that's not a font, but close in style.
