I am not sure where the blue "eye-ring" (central iris heterochromia) gene came from and when; my grandfather’s generation did have very strong Eurasian facial characteristics. My mother's generation has two and none in our generation. There were no colored pictures from previous generations and our family’s history book did not record anyone’s appearance, only how successful the person was. My grandfather’s older brother’s son did have blue eyes.
