Need help with these names!! Going nuts!?

keep in mind, nobody is going to be saying harlow amy blah lastname or vallon trace blah lastname. they are going to be saying harlow lastname or vallon lastname and thats what really needs to sound good. I actually like Harlow and Vallon BOTH better as middle names anyway, because weirder names are better in the middle where the child doesnt have to use them all the time in grade school if they dont want, plus if there are a billion harlows your child wont have to worry. Trace and Amy are both great first names.
