My stepsister is JoEllen, after her father Joe, and her mother, Helen. However, my stepmother's birth certificate says her name is Helene! We didn't discover that until she was in her 70's or 80's and the date on there was a different year too. She was born in the "country" in 1915 (or 16 :-) at her grandmother's home/farm so who knows whether it was the country doctor's/"recorder's" fault or what.
