WikiTree’s connection with the Islendingabok?

Question

What ancestral connection have you found between WikiTree’s One World Tree and the Islendingabok (Íslendingabók) , Icelandic genealogical database?

https://en.m.wikipedia.org/wiki/%C3%8Dslendingab%C3%B3k#Modern_incarnation ?

I want to believe that a few of the early ancestral lines of Europe have an ancestor who is in both databases.  However I not yet found that connection.

For example, is there a living WikiTree user in “Scotland” who traces back to a Norse Viking and that Viking’s living descendant is found in both the Islendingabok and WikiTree?

Thanks and sincerely,
