"Thorsteinn Raudskeggr.
Name change from Ivan Ivanovitch Serebrenikov.
Submitted as Thorsteinn Raudskeggr, the name was changed at kingdom to Thorsteinn raudskeggr. As the Cover Letter discusses, we have removed the requirement that descriptive bynames in Old Norse be capitalized. Thus we can restore this to the submitted form.
The submitter's previous name, Ivan Ivanovitch Serebrenikov, is retained as an alternate name."
