William Henry and Russell (at least) both have that cleft in their chin. The beard of Benj leaves his chin a ??? Maybe there’s a younger/beardless pic available?
I googled for as much time as I had (need to mow the law before the rain comes) but I was unable to find a pic of old Ben without a beard. Even as a young man he wore a full beard. One website noted that Benjamin Harrison was the last bearded president that the US has had. I thought that the harrisons all had a similar brow line. There are other pictures of William Henry harrison that show it better.
The reason I picked on the Harrisons to show family resemblances is that I once saw a program on TV narrated by one of their descendents. I think it was America’s Castles. Anyhow, there was a modern day descendent that was the spitting image of his ancestors narrating the program. They all seemed to share a very long nose. The pictures I posted don’t show it as much, but it was really remarkable in the TV show (they showed some old paintings on the house tour.)
