She's kind of named after Joni Eareckson Tada, and kind of named after Ian -- Joni is a name derived from the same Hebrew name as Ian, יוֹחָנָן which means "יהוה, (God) is Gracious" -- and kind of named after Juliane -- Joni sounds like Juliane -- and kind of named after Confucius -- Confucius' 字 (courtesy name) was 仲尼 and we feminized it by adding the 女 radical.
Why Confucius? Well, actually we chose the English name first and then only came up with a Chinese name that sounds similar. My father came up with a bunch of suggestions for Chinese names and presented them to us. I like a lot of what I have read of Confucius' original teachings (or supposed original teachings, since Emperor Qin Shi Huang 秦始皇 destroyed his original works) for a lot of it sounds very Biblical -- including the Golden Rule. So of all the suggestions my father made, I liked this one best, and Juliane was agreeable to that suggestion.
