Well, I agree on the "translation" argument, should just be called "equivalents" in the case of proper names. I'll try to help, although most of these don't have a translation:
Brennan - N/A
Evan - According to behind the name website it's derived from John, in which case it would be Juan, otherwise... it doesn't have an equivalent
Brittany - N/A
Alyssa - Alyssa
Jasmine - Jazmín
Sammantha - Samanta
Laura - Laura
Kelsey - N/A
Hilary - Hilaria
Courtney - N/A
