[Facts] Re: "Candasie" or "Kandasie"
Yes, it is undoubtedly a respelling of "Candace". Candace was commonly pronounced "can-DAY-suh" or "CAN-duh-see" during the 19th century in the USA; the "CAN-diss" pronunciation is more modern. There were quite a few women in the Southern part of the USA in the 19th century called Dacey or Dacie because they were named after a Candace.
