What are your opinions on these names? :)?

To me they generally sound kind of old-fashioned, too y, and/or contrived. If I had to pick, I'd pick Evan Nathaniel for a boy and Evelyn Grace for a girl. I'd pick these names because you have to think of your child possibly becoming a CEO of some company someday, and sometimes a stodgy, phony, or too y name can work against them in the business world.
