Its not dated to me, I like it but I prefer
Jessa or
Jessamine a bit more.
I have known about 3 or 4 Jessicas including my cousin
Jessica Erin. Pretty much all were teenagers or younger.
I don't like
Jessie (I like
Jesse for a boy) but
Jess and
Jessa are fine as a nn for
Jessica or
Jessamine. I like
Jessa on its own too.
I used to know a girl named Jeska.
