Meaning & origin
Lucillia is an extremely rare name in the United States, first recorded in 2010 according to Social Security data. Its 2025 rank of 7,491, with a frequency of about 1 in 114,805 births, places it among the most uncommon choices. The name reached its peak popularity in 2025, coinciding with its most recent year of data, though the low numbers suggest it remains a niche selection. As a modern elaboration of the classic Lucy, Lucillia offers a distinctively elaborate sound without breaking away from familiar roots. Given its recent debut and stable but minimal usage, Lucillia appeals to parents seeking uniqueness within the trend of vintage-sounding, feminine names ending in -ia.
Lucillia appears to be a modern, elaborate spelling of the name Lucy, which derives from the Latin lux 'light'. It may also be a variant of Lucilia, a feminine form of the Roman family name Lucilius. The name gained slight use in the United States in the 2010s, likely as a creative respelling aimed at distinctiveness.
