But then the Lightwoods adopted Jace after Valentine gave him to them. I don't think Valentine really gave Jace a name. I think he was just "Jonathan Cristopher's replacement" or just "an experiment". I guess Valentine called Jace Jonathan since Jace was like Jonathan Experiment #2. And I'm pretty sure it said in the books that Maryse was the one to call Jace Jace.
