Lillian is having a remarkable revival, now near the Top 20, the highest it's been since the 1920's. It was a Top 10 name in its Lillian Gish-Lillian (born Helen Louise) Russell-Floradora Girl heyday at the turn of the last century.
Now, with its trendy multi-L sounds, Lillian is seen by parents as a more serious and subdued cousin of the megapopular Lily. Lilian is another spelling.
TV actress Mary McCormack and director Baz Luhrmann both have daughters named Lillian.
