I had an uncle, Jede, who was called that almost all of his life, that and Jedon. Census records, a death certificate, gravestone, etc. My grandfather always called him that. However, in the very first census he shows up in, the name is GIDEON. I found out later that “Jede” or “Jead” is a nickname for Gideon. So, on his profile Gideon is his first name, and Jede is in the nickname field, even though Jede was the name he was known all his life and what he called himself. If I only put Jede in the prename field, Gideon wouldn’t be known.
