Gregg,

It is an interesting question. Here are my thoughts.

Your primary objective is to sort out the five brothers. That is apt to be
a difficult task, possibly requiring a favorable roll of the dice. Doing
the test on grandson rather than grandpa risks a disrupting mutation,
without contributing much value. A mutation since grandpa would be not very
useful because it hasn't been inherited enough times, and you wouldn't know
it was recent. You surely have other better ways to get information about
the last three generations. Discovering a non-paternity event is recent
generations might be interesting, but it would certainly interfere with your
primary mission.

I would adapt the strategy most likely to resolve the three brothers
question.

Best wishes,
