My first post here was incorrect.

I was part-way through my analysis and forgot to include the 4th condition.
But it does look like there is an incompatibility as pointed out by Kenny M.

Unless there is something unexpected:
a) a 4th brother
b) someone with 2 eyes of different colors
but both of these are ruled out by KS's comment
or
c) Unexpected details related to the definition of hazel eye color.  My understanding is that it essentially a blend or mosaic of different colors.  Maybe the puzzle solution requires that someone's eye color could be both hazel and another color at the same time.
