Help: want a namesake AND style

New Mama
We found out we're having a girl and want to honor my late grandmother Mary Carol.  Any combo or dirivitive (I want it to be a clear namesake, tho) is an option.  Another thing I'd like to work it, but less important, is a middle name of Rose.  I don't know how I'd do both, but Mary or Carol comes first!  Any ideas?  I'm finding it hard to come up with a stylish namesake that my husband and I can agree on. Thanks!
