You can't be too cossetted and cosy if you're determined to find this author. You just have to look through this longish list, author by author!
Remember that Icelandic people are listed by forename [i.e. Christian name] as they change their surname every generation, as Icelanders are given a forename, but the surname is the name of their father + -son or -dóttir. Note that women are still their father's daughter in their surnames, not their mother's daughter. Whether feminists are changing this I do not know. Example: Áslaug Jónsdóttir, i.e. Áslaug Daughter-of-John.
