Meaning & origin

Lillar is an exceptionally rare name that first appeared in U.S. records in 1894 with fewer than five births that year. Its peak year was also 1894, and it has never ranked among the top 1000 names. The name's trajectory is stable, meaning it has remained at very low usage levels for decades. The origin of Lillar is uncertain; it may have been a variant of the more familiar Lillah or a creative formation from the popular Lily. Because of its rarity, Lillar is not associated with any particular region or cultural tradition.

Lillar is a rare name of uncertain origin. It may be a variant of Lillah, which itself is a diminutive of names like Lilian or Lily, or it could be a coined name from the late 19th century. The name appeared in the United States in 1894 with very few recorded births, and its usage has remained sporadic and extremely rare ever since.
