But I was guessing at Bjork's father's name. All I know for sure is it starts with a 'G'. I think at the time I read about it, Bjork was considered a single mum and I think she was causing waves by saying her kids' surnames would be Bjorksson or Bjorksdottir. Other than that, I had forgotten the patronymy vs matronymy aspect.
And yes, I did already know about the "Andersson" => "Anderson" progression. I am a casual student of the history of language and words and this includes names. I first discovered this construct many years ago when a friend's father worked for Ericsson and I noticed the double S. :-)
Wade, who would be surnamed Brucesson with such a naming convention.
