My great-grandfather.
My great-grandfather with my grandfather.
My grandfather with his two sisters.
Given that my grandfather was born in 1908, I estimate these at around 1909-1910. Around one hundred years ago. I love looking at old pictures, like these, in antique stores. But, as much as I enjoy looking at them, I'm always a little saddened by the fact that the subjects are lost to history and no one will ever know who they were.
