The Bluest of Eyes, where did they come from?

I look at Gabriel everyday and think "whose baby is this?" He has the bluest eyes, and with me, Danny, and Christian all sharing brown eyes, we wonder how on earth it happened! Well I kinda know, my mom's side is all blue eyed. Gabriel actually looks just my older brother did as a baby, the same eyes and hair color. As he gets older his hair gets a little more reddish brown too. I love it.
