My daughter (8 now) has this same trait. Left “blue” eye has brown spot/line from pupil to lower part of blue in eye. Symmetrically vertical.

Characteristics; strawberry blonde hair, blue eyes. She is very tall for her age.

My wife and I are her biological parents.

Family Ancestry:

My father’s father is Latin (from Cantabria--Arredondo, Spain); hence our last name.
My father’s mother is Mexican (Michoacán, Mexico)
My mother’s father is Irish/Scottish (Clan Wallace)
My mother’s mother is a Jewish Cherokee Indian from Chattanooga, TN (5th generation)

Wife’s father is Latin (Cuba – 2nd generation; migrated to Florida in late 1800’s)
Wife’s mother is Latin (Asturias, Spain – family arrived in Florida in mid 1900’s)

Royalty? Well, we have a city in Spain and a city in Florida named after my Father’s Family so…who knows. LOL
