Molly is one of the original nickname names, ALWAYS ranking among the US Top 500 girl names since statistics began, in 1880. Molly peaked in 1991 only to rise just as high again in 2011, and though softening retains a good measure of popularity and charm.

Mary is the English form of Maria, which ultimately was derived from the Hebrew name Maryam/Mariam. The original meaning of Maryam is uncertain, but theories include "drop of the sea" (from Hebrew roots mar "drop" and yam "sea"); "bitter" (from Hebrew marah "bitterness"); and "beloved" (from the Egyptian root mr).

Bright and vivid, Marisol is a sunny name of Spanish origin and an excellent candidate to cross languages, a la Soledad, Paz, and Solana. Familiar in its native Spain (though no longer a top choice), a recent year also saw Marisol make the Top 1000 in the US, the Top 200 in Italy, and the Top 100 in Mexico.

The car, by the way was named after the eleven-year-old daughter of the Daimler company's French distributor in 1901.

Sweet, nicknamey name belonging to the tragic heroines of both La Bohème and Rent. Mimi might feel too slight for many parents to use on the birth certificate, but as a short form, it's one of the cutest of the cute baby names.

Maris is an unusual and appealing name that has never appeared in the U.S. Top 1000, overshadowed by its twentieth century elaboration, Marisa/Marissa. It derives from the phrase "Stella Maris," star of the sea, one of the many epithets of the Virgin Mary, and became familiar via the unseen (but unliked) character of sitcom Frasier's ex-sister-in-law.

Almost as popular in the 1950s among the Irish in Boston as it was with those back in Bray, Maureen was once among the most prominent Irish names for girls in the US but has fallen from favor along with most of her een-ending sisters such as Eileen and Colleen.
