Bigamy is a word that can send shudders through a family but, for family historians, it offers a chance to really get to know an ancestor - and their faults. A number of bigamists bearing the name of Cave, along with several other bigamists who have interesting backgrounds, are in this book, which is published in conjunction with the 2015 Annual Gathering of the Cave Family History Society. Far from being an academic volume, it tries to explain the why, wherefore and how behind these individuals and their crime.
