To note: all three are blond, ellie's eyes are brown, her brothers are blue.
Ellie's father is homozygous for eye colour but her mother is heterozygous. She passed a 'blue eye' gene to the boys and a 'brown eye' gene to Ellie. Brown hair is dominant over blond but ellie and her brothers are all blond.

Some of the Geneology Tutorials should be of help:
