Chestnut brown eye color on asians?

Is it rare for asians to have chestnut brown eyes? My father and I are the only ones in our family with really light-brown/reddish eyes, and its really unusal compared to our other relatives (we're chinese). Also my father and I have red strands of hair, I'm the only one in my family with hair that curls into ringlets. Are these traits more common than I think they are? My father's mother's side has Possible english/dutch heritage but I don't really rely on that
