Consideration has been given to each and every generation of the Greene's family, every person in this book being has been scrutinised in minute details. They have been thoroughly researched, all the way from 1160 until the 20th century. With a clear concise picture of who the Greene family were, and more importantly where they came from, or how they contributed to shaping the History of England, no stone has been left unturned. My focus has been on the English Greene's as well as the America, Irish and Welsh Greene family members.
