If it was a girl, I would likely suggest a name related to a flower or plant of some sort (Lily, Daisy, Rose), or a month (April, May, June). Other possibilities (in no particular order): Ashley, Mia, Cecilia, Michelle, Jenna, Lucy, Amy, Mary, Alice, Ann (I understand some of those are religious in nature, but I don't mind for a girl).
If it was a boy, I would likely suggest the first normal-sounding name whose origins weren't religious that came to mind.
Either way, I'd leave the decision up to my wife (unless she suggested something outrageous).
