I am deeply indebted to Pam Vowles from England who researched meticulously the Marsters family tree and also provided a wealth of other valuable information. I am very grateful as well to William's great great granddaugher, Yolande Browne (now deceased) from New Zealand for her research and detailed family knowledge, and the Davies family of France who did valuable research in the UK's national archives, subsequently supplemented by my own research.
