I want my main character’s name to be [name]Jessie[/name], but I don’t want to use [name]Jessica[/name] as her full name unless I have to.
Suggestions please 
I’ve actually been thinking about this for a random reason, and sadly [name]Jessamine[/name] is the only really legitimate alternative to [name]Jessica[/name].
[name]Jessie[/name] by itself is an option, as are inventions like:
Jesselyn
Jessaleen
Jessabeth
Jessavette
[name]Just[/name] made these up on the top of my head… but you get the idea!
[name]Jessamine[/name] and [name]Jessamy[/name] are the only ones I can think of. Maybe [name]Jasmine[/name] could work? [name]Jessie[/name] definitely could work by itself.
[name]Jessamyn[/name] and [name]Jessa[/name] are the only others, I think
I am a [name]Jessie[/name] (just [name]Jessie[/name]); if I had to “formalize” my name, I would either be [name]Jamesina[/name] or [name]Jessamyn[/name]. My bestfriend has christened me Jesscia ([name]Jess[/name]-see-ah) because she knows my disdain of [name]Jessica[/name]. 
The more I look at it, the more I like [name]Jessamine[/name]/[name]Jessamyn[/name].
And it’s certainly easier than going the complex route I was trying for at one point, that her initials were JES or JSS (her last name is [name]Shepherd[/name])
Thanks, berries! You rock!
In [name]Scotland[/name], [name]Jessie[/name] is a nickname for [name]Janet[/name] which in turn can be a nickname for [name]Jane[/name].
Arkalai because it is swedish for [name]Jessica[/name] and no one can say it right so she gooes by [name]Jessie[/name]. Or a variation of [name]Jessica[/name] in another language.
[name]Jessa[/name]
[name]Jesenia[/name]
Thanks all I decided I’m going with either [name]Jessamy[/name] or [name]Jessamine[/name].
