Julie, there is a Benjamin Frankin Zellers buried in the Catholic Cemetary in Cannelton, Indiana.I believe it is called Clifton Cemetary, not sure.
My Grandfather William Everett Zellers used to tell stories about how "Benny" was a spry old guy who once swam across the Ohio river on his 80th birthday.If it is true I am not sure, my grandfather was quite the story teller.
My parents (William Arthur Zellers and Patricia Ann (Shearn) Zellers) have a very complete genealogy back to Germany that was done by a distant family member from Nevada. If interested, i can scan this for you and pass along.
My email is email@example.com if you want to get in touch directly.
