About to publish my book on the history of the Semples/Sempills. It will be available soon through Amazon: "The Semples/Lord Sempills of West Scotland: family and contextual history from 11th to 19th Centuries". If you can trace your ancestors back to the any Lord Sempill then, with this book, you can also trace back to English and Scottish royalty. An old book "Genealogical History of the Family Semple from 1214 to 1888" by Willam Alexander Semple, available from Amazon Canada, lists a lot of descendents of Lord Sempills.
