I love this name. I've only met one Jerusha, an acquaintance that my daughter had about six or seven years ago. I remember feeling admiration for her parents for giving her such a beautiful, yet underused name.
It seems a lot of people find it too strange. Sometimes I feel that it sounds like it should be the name of one of the horrid kids in "Willie Wonka and the Chocolate Factory," but...no, I still love it.
What do you think of Jerusha?
