From left to right -- Gladys, Harold and Dorothy Cooper.
My grandfather was the youngest sibling, but he wasn't yet born when this picture was taken -- the photo's from before 1918, then.
The Coopers lived in Doniphan, Kansas and later moved into Atchison (the "big" town); Doniphan is now just the cemetery, a couple of houses and the Catholic church (with an altar that my great-great grandfather may have built). Atchison is bigger, but it's still a very small town -- It's near St. Joseph, Missouri, but far enough away from St. Joe and Kansas City that they haven't been able to attract any sort of tourism. Not that there's a whole lot to do.
Atchison does have some nice Victorian mansions and a cool train museum, but it's so out of the way that most people don't get to see it.
By the way, I love the giant bow in my Aunt Dorothy's hair.
