All I can think of is James Thurber's mention of a Juanemma:
"Juanemma Kramer was one of my favorites. Her mother loved the name Juanita so dearly that she worked the first part of it into the names of all her daughters -- they were (in addition to a Juanita) Juanemma, Juanhelen, and Juangrace."

I would point out that I also dated an otherwise wellmeaning man who objected to my fondness for the name Johanna (prounced YoHanna) as a child's name, and admitted on cross questioning that it was because the name "sounded Black" to him.
