I have the book you are looking for: "Edward fitz Randolph Branch Lines, Allied Families and English and Norman Ancestry", which was compiled & published by Oris H. Fitz Randolph in 1976. If you want me to extract data from it relating to your line, I would be glad to assist you.
I also have the book "Fitz Randolph Genealogy" which was privately published in 1950 by Louise Aymar Christian & Howard Stelle Fitz Randolph; and the book "Fitz Randolph Traditions, A Story of a Thousand Years" authored by L.V.F. Randolph and published in 1907 by the New Jersey Historical Society. I also have various other Fitz Randolph source material.
My Fitz Ranolph descent is: Edward Fitz Randolph --> Thomas Fitz Randolph --> Jonathan Fitz Randolph --> Phineas Fitz Randolph --> Ezekiel Fitz Randolph --> Hannah Fitz Randolph --> Frances Low --> Abram Ballard Davis --> Amy Ballard Davis --> Edwin George Bal --> Eric Bal (me).
