I like Karen,Pamela and
Diane. The rest are too common in mom/grandmas.
My piano teacher(who's about 50) is named
Linda Phyllis J. and she had to go by
Phyllis ever since kindergarten when there were 5 Lindas in her class, and two of them were
Linda J, so she went by her middle name.
I also have some 60's names for you:
MichelleSharonLisaSandra/Sandy
I think
Lisa,
Michelle and
Sandra will come back.
Sharon might be spelled creatively, like
Sharyn or something like that.
