A Swedish historian, Dick Harrisson, claims that most info on the legendary nordic kings from viking time is unreliable redagarding their family relations - allthough they likely existed. And all legendary kings from before the viking time (before about 800) should be conciderd fictional, since they are only supported by nordic saga literature (written down during the 13th and 14th centuries) and other non-concurrent literature. No other literature exists from before viking time, and almost no other literature from viking time. I think this is true for all the Nordic countries.
People often make fun of Geni because of all these saga kings and religious figures. It is not possible to delete them all from Geni - people will put them back. I suggest that we always mark them as "legendary king", "fairy king" or "fictional" in the title field. This warning will be clearly visible in the tree, and will show that at least some level of scientific scepticism exiests at Geni. Please help me to mark hem like this. I do not have access to all profiles.
