https://en.wikipedia.org/wiki/Icelandic_name https://en.wikipedia.org/wiki/Icelandic_name gives an Icelandic example of Stefán Gunnarsson with children named Harpa Stefánsdóttir and Róbert Stefánsson. Björk's name is Björk Guðmundsdóttir, daughter of Guðmundur Gunnarsson and Hildur Rúna Hauksdóttir. These use the genitive -s followed by either -dóttir for girls or -son for boys. In Iceland, matching parents and their kids by their last names doesn't work that well.
