Lillian, an elaborated form of Lily and shortened form of Liliana, is derived from the Latin word lilium, referring to the lily flower. It was a top-100 girl's name in the United States every year between 1900 and 1940 before nearly dropping out of the top-500 in the late-1970s. Lillian has since made a comeback and has now been a top-100 girl's name every year since 2002, per the Social Security Administration. It's also the middle name "Pitch Perfect" star Rebel Wilson chose for her daughter Royce Lillian, born in 2022.
