No matter which profession your ancestors chose, they generally had one thing in common; what they lacked in stability and common sense, they made up for in guts and glory. Clergy may have been deemed heretical at some point, and soldiers might have led a group of mutineers. This name suggests your ~ancestor~ ancestors were often obstinate and disagreeable. This trait was probably counterproductive at times but may have also provided the motivation to triumph over adversity.
