Alis, though she is clearly a lady with style and very good taste!!
I thought of Balthazar because you mentioned Gabriel, and it's a similar type of name with links to Christmas.
I quite like Torin, but think it is a bit too LOTR for me.
Whatever name you pick, your son will be adorable, and he and his name will meld together into your own beloved child.
