My name is Jenny O'Brien. It didn't used to be I was named John O'Brien. So let me tell you how this happened.
My folks are at least part Irish along with a mixed bag of many other nationalities. Any towering mountain of a man Irish genes that may have existed are long gone, replaced by what could almost be described as elfin genes. Both of my parents are small.
Not just the height though as both of them are under 5foot 5. My Mom is only 5'2 while my Dad is 5'4 or 5'6 with shoes on.
