The name Meg is a girl's name of English, Greek origin meaning "pearl". Meg and is often added to lists like Baby Names from Children's Books and discussed in our forums with posts like "The Makeover Baby Name Game".
From the experts:
Meg, perennially one of the Little Women, is a Margaret short form that manages to be neither quite in nor quite out of style. Meg is sleeker and more sophisticated than Maggie, more contemporary than Peg, more stylish than Megan, and still one of the best diminutives of Margaret.
