"I was the only redhead in the family plus I have green eyes and freckles."

My Mother (Northern Irish) was very fair: sea blue eyes and light blonde hair. Both her parents had blue eyes too, though one was fair and one was dark. Her brother inherited the dark hair with dark blue eyes. On my fathers side the family come from Liverpool Irish: all blonde or dark hair and blue eyes yet again.
I'm the only green eyed member of my immediate family. I don't have any especially discernable Irish characteristics either. Though friends of mine who are members of the Irish diaspora can be striking in their classic Irish appearance.
