A culmination of more than 30 years of research, this first volume (in a series of 10) gives us the ancestors of Prince Henry Sinclair, showing how he came to be the Earl of Scotland the Jarl of Orkney, a protectorate of Norway. While only the first four generations of his descendants are represented here, each of his children (and their spouses) descendants will be offered in the following volumes. This is done in order to keep each volume under 400 pages and to include all the necessary sources at a reasonable price. This volume also includes a full list of the persons represented in the final file but does not include their relationships to Prince Henry. They will each be addressed in future volumes. Omissions, corrections, and additions may be sent to the author for inclusion in a future version. Proceeds from the sale of this book will go to further the research into Prince Henry and his voyages to America. Please enjoy!
