From someones DNA in the past family tree. It happens. search your family tree and you will find your answer.

No, not genetically possible. Don't know about the hair, but the eyes must be blue if both parents have blue eyes. Blue eyes are a recessive gene trait. A person with brown eyes can have a recessive blue gene, but a person with blue eyes must have both blue genes. Since neither parent can have a dominant brown eye gene, (This would make them brown eyed) there are no brown eyed genes for the child to get.

I don't think they can have a baby with brown eyes because with blue eyes they both have recessive genes and do not carry a dominant gene.

It's called the Mailman effect.
