DM has blue, as did both her parents, DF had hazel, his DM had brown, his DF had blue
out of 4 kids everybody has blue except me, I have hazel
my DH has brown, my kids are one each of hazel, blue, and brown. I was really surprised with the blue, especially since the blue and brown are twins.
DH's family: his DM has brown, DF had blue, out of 8 kids only one has blue, the rest are all brown.
