Today I was flipping around one of those dangerous clickbait ad sites where you should never go but this link will take you there, to 75 Rare and Mind-Blowing Historical Photos, just killin off some time, and I came across this:
Yes, it's for sure my great grandparents. They were my aunt's parents and she recognized them. As a matter of fact, at the time I got the picture I was working for someone with the same last name as my great grandparents. (They are my father's maternal parents so aren't creds.) He looks almost exactly like this picture of my great grandfather. We compared family trees and as I recall, our great great grandfathers were probably brothers. My ancestor stayed in Philadelphia where the family had entered the country in the mid 19th century and his went to Kentucky.
God, I love the internet.
