Six fingers and toes do not a Nephilum make. I have read, fifty five years ago, that Ann Boleyn, mother of Queen Elizabeth, was said to have had six fingers on one hand.
The people of Cervera de Buitrago in Spain often have the six fingers.
Same for the Da Silva family from Brazil.

I understand that. In fact I knew a kid in 4th grade that had six toes. He was not a giant. But it is typical of Giants. Both the pictures of skeletons, as well as ancient descriptions.
