Formal name for Dana

There is a character in my story that goes by the nickname [name_u]Dana[/name_u]. I don’t want this to be her formal name but I can’t find a suitable choice. There is a character named [name_f]Danika[/name_f] in honor of her, so that isn’t an option.

Names I have considered but don’t like :
[name_f]Danielle[/name_f] / [name_f]Daniella[/name_f]

I’m looking for something unusual as my characters don’t believe in sharing names amongst the living, so names are often elaborations or diminutives (but no cre8tive spellings, please). [name_f]TIA[/name_f]!

[name_f]Danula[/name_f] is the only one I can think of

I kind of like [name_f]Dariya[/name_f] but idk if [name_u]Dana[/name_u] is too much of a stretch. I like the sounds of [name_u]Dagny[/name_u] and [name_f]Dagmar[/name_f] but they aren’t fitting the character. Same with [name_f]Danula[/name_f]

I like the names Danina, Danelly, Dorana, Danthe, and [name_f]Daphne[/name_f].

Maybe [name_f]Jordana[/name_f]?

I never considered [name_f]Jordana[/name_f], I actually love that name! Thanks
