Source Forms: Caecilia

Popularity: The name Cecily ranked 1827th in popularity for females of all ages in a sample of the 1990 US Census.

Though this name appears on the 1990 U.S. Census lists, it is used by only a small percentage of the general population.

Narrative: This ancient Roman family name gave rise to the feminine Cecilia, which in time developed into Cecile and Cecily.

Although those names are usually considered female equivalents of the male Cecil, that name probably descended from a Welsh original, Seissylt, meaning ''the sixth child.''
