I like the name
Shirley with the more classical spelling of "
Shirley" although not enough to use it personally. I personally know a
Shirlee in her twenties, and I think there is a tendency upon hearing the name to assume the original spelling. It is not too old fashioned or frumpy. Names have a tendency to be cyclical, so I can see it being used again since the
Shirley Temple craze has died down. You might get away with using
Meadow as a middle name, but for a first name the hippie connotations are too strong.
