Elizabeth, I don't see a son William attached to Rachel Jones and this profile in WikiTree is not properly sourced with primary source documentation. This family would need proper primary source documentation to firmly establish the various family relationships.
Is James the son of William? If so, I would start downstream wherever you have primary source documentation for the relationships and then work your way back one step at a time using primary sources.
I would edit your question and add the tag united_states and also the state names of the involved states. That will help get well-trained eyes on your question.
