In my research of my French Huguenot ancestors the discovery of Robin Gwynn's book was the high point - a treasure. This book is concise, well-organized and written in elegant prose. It illuminated and enriched my understanding of that part of our history. I could hardly put it down.
For others who are researching Huguenot ancestors who first settled in Colonial South Carolina, I also recommend Arthur H. Hirsch's THE HUGUENOTS OF COLONIAL SOUTH CAROLINA, University of South Carolina Press. This second book, while not as concise, elegant or well illustrated; is the best source I have found on its subject.
