Overview

• The 35-name roster features Stuart or Stewart, Spencer, Plantagenet, Tudor, Windsor and continental houses such as Bourbon, Habsburg and Romanov.
• U.S. Census data show large numbers of these surnames in America, including 324,957 Stewarts, 264,826 Howards and 7,621 Windsors.
• Several entries have multiple spellings or forms, such as Stewart and Stuart, Darcy and d’Arcy, and Capell and Capel.
• MyHeritage cautions that a shared surname does not establish royal lineage, urging research through censuses, vital records and other historical documents.
• Some coverage notes studies suggesting thousands could hold potential claims to the British crown, though the new list does not validate those assertions.
