I have removed a generation (Áslákur Björnsson) between Hróald and Bjarn to align the tree with https://www.snerpa.is/net/snorri/landnama.htm rather than http://heimskringla.no/wiki/Landnamabogen_3
As per the Landnamabok project, https://www.geni.com/projects/Landn%25C3%25A1mab%25C3%25B3k-The-Boo..., Sturlubók is our preferred source.
