I like
Lillian. It's not a name that is popular among my age group, but as popular as it is among little girls these days, I'm sure there are quite a few who go by their full names rather than
Lily. It ranked #22 in the U.S. last year, but popularity varies by state and even by region. I live in the U.S., but it doesn't seem to be that popular where I live in comparison to other parts of the U.S. I can't speak for every country in
Europe, but going by the top 100 lists from European countries that I've seen, it doesn't seem to be very popular.
