I named my daughter Jessamy in 1990. I got the name from a book by the same name I had read when I was about ten or eleven. It was the first book I read about time travel. I loved the book and the name. My husband and I couldn't agree on any other name. It was hard in a way to name my child a name that was different. We call her Jessy for short. It took me almost two years to decide to spell it that way. I knew that Jessie would be more normal but Jessy seem correct to me.
I don't think this is what you are looking for but oh well...
