Hello Larry! We must be related! Your grandfather and mine were brothers. My grandfather is Frank, the one you visited. As far as we can tell Grandpa Frank was married 5 times!!! We believe my dad (another Frank) is his oldest son. That's so interesting that he looked alot like your grandpa Bart. We never got to meet any of Grandpa Frank's family, so this is great that you are able to share that tidbit with us! Are there many Dolfin's still in Michigan?
