Bertrada of Laon is one of the very few women of the century about whom we can know anything more than just a name and a marital disposition. But from what we can see of her, particularly one series of events late in her life, she must have been a formidable lady.
She was born sometime between 710 and 727, in Laon, France, of noble parents. After that, we get nothing until she reappears as the wife of Pepin about 741, and the details immediately get fuzzy. No one is sure if she was Pepin’s first or second wife. In fact, it is hard to be sure just what a wife was back then, as the line between wife and concubine was not well defined. Also fuzzy were the rules on who could marry whom, based on how closely they were related. Always a problem when the 1% keep marrying each other.
