I am not sure of my info on Holmes B. Smith but I have his parents as John Smith and Sarah Boisseau. Not Proven. I have Sarah the daughter of Holmes Boisseau and Rebecca. John Smith' s parent Richard Smith and Jane. John born about 1694 to 1700.
My source for this info was found in the "Virginians: The Family History of Richard Smith" by John W. Pritchett. It lists the descendants of Richard Smith and Jane. This is how it lists this JOhn.
John Smith, Holmes Boisseau, Holmes B. Smith,
That is how I connected Holmes B. to John Smith.
