His alleged Red Bolling parents are here

They had a lot of kids and many died young, probably including some we don't know. The list of those who survived their father is from his will and from the book written by the 3rd surviving son, Robert, in 1764.

They didn't have a James who lived until 1826. This means James isn't a Pocahontas Descendant - there was only the one Red Bolling family in that generation.
Presumably he got detached and cast loose back when all the other Blue Bollings were detached. Many of those are completely fictitious and can't be sourced except in the novel they appear in.
