Four people are sitting around a campfire after a long day of recreation, when one man comments: "Do you realize that around this campfire, the four of us include a mother, father, brother, sister, son, daughter, niece, nephew, aunt, uncle and a couple of cousins"?.
If everyone is related by blood (with no unusual marriages) how is this possible?

This was an interesting problem, but I am a little disappointed by the wording.  As pointed out by a couple of folks, the problem does not claim that the several relationships suggested by the labels hold between the people around the fire.  As it is worded, there's a great, great, great, great grandson there, as well.

still, thank you for the problem!
