This is a good start for now but it still may need future expansion to include stuff in more detail and replace the unreliable sources (genealogy websites and blog entries). --KAVEBEAR (talk) 20:53, 10 January 2017 (UTC)Reply
The Beckley family was extremely interconnected with the Afongs, the Sumners, the Stillmans, the Cummins, the Davisons, the Kaheas, the Crowningsburg, the (Wray) Taylors, the Pitmans, etc, which all had common Hawaiian descent from Hoolulu or Kahānui and Kahaʻopulani. This is an incomplete expansion of the family tree from his eldest son and their descendants. Their were so many descendants and doesn't include the maternal extensions of the family.
