I like Lilah best. I only know one, and she adopted the name for herself. It is defined on other websites as meaning "languishing, lovelorn, seductive; night beauty."
I think
Laura has a lovely sound to it, but I have known so many of them. I can't emphasize enough HOW MANY! Unfortunately, they have all shared the same personality traits of being stuck up and mean (please, no offense to any Lauras! I am only thinking of the ones I have known personally).
I do have one friend named
Laurel, she goes by
Laurie for short, and she is one of the most intelligent, interesting, and kindest people I have ever known. I think it is less common then
Laura, so if you really like that "r" sound, you might want to consider that alternative.
