The version I have from Norwegian contacts is that Dahl regarded himself as Australian. Hence the name change from Karl Edwart to Charles Edward. He spent much of his life here but I'm doubtful about some of the material on this site. In particular, I've found no trace of him in Adelaide, where I live. Although there are certain dates that don't match up, I'm wondering whether he was the Charles Dahl who lived for a time in Adelaide Street, Brisbane, but I lack the resources to research material that's only available in Queensland.
