Yankee you can't get things right tonight can you?
I'll spell it out for you then.
Any father is also a son, so that leaves 4.
2 of those four can be grandfathers, so that STILL leaves 4 as minimum.
Tsk tsk tsk ;-)

I also go with 6

1 = Grandpa who is also a father
2 = Grandpa who is also a father
3 = Father who is also a son
4 = Father who is also a son
5 = Son
6 = Son

So if you count this you get 2 x Grandpas, 4 fathers, 4 sons.

Maybe I'm wrong, but thats how I see this.
