I hate both
Saffron and
Serge.
Serge reminds me of Surge, as in
Storm Surge. Also, people in my family nickname Surgeries "Surge".
The only names from the list I like are
Justin and
Sarah (I actually have two best friends with those names :) ) I also like
Fleur as a middle name, but it reminds me too much of Flour. If I were to make Combos I would say
Sarah Fleur and
Justin Oliver (also it's cute that it has both of the couple's names.)
The rest of the names I don't like at all, really.
