An Unusual Genealogy Search

My grand mother, Pauline Mae Stuckey (nee Hockley)18 July 1921 - 19 May 2000 had an unusual foot feature which she passed down to my mother and then 2 of my neices. It has to be a feature she received through one of her parents George Washington Hockley or Sadie Mae Clemens. The feature is that the 2nd toe (beside her big toe) on both feet was smaller than both the big toe and the 3rd toe. I know that this is an odd thing to write about in a genealogy forum, but it has caused several in my family to become curious. We are trying to determine if it is a Hockley Trait or a Clemens trait. She was born and raised in Lebanon County, Pennsylvania and had family in Pine Grove, PA. Please contact me if this is a feature that you may have noticed in your family. Thanks for bearing with me.
