In the early days of Google, I googled myself as was popular at the time. That search revealed nothing about me (what did I expect); then, I googled my grandfather, Edgar Mowbray Henderson, and found this link at the top of the results. Imagine my surprise when I followed that link and saw the names of my paternal grandparents. Imagine my shock when I clicked on the link that followed revealing this unexpected image of their gravestone.
Exploring that site further, revealed the gravestones of my great grandparents and my great great grandparents.
