In tandem with the longer-form Natalia, this pretty Russian-flavored name has been rising in the popularity charts in the US; it entered the Top 300 for the first time in 2015.
In the mythology of one ancient sect, Talia was one of ten angels who attended the sun on its daily course. A prominent bearer is Talia Shire, doomed to go down in cinema history as Rocky's mousy girlfriend Adrienne, along with actress Talia Balsam, aka the former Mrs. George Clooney. Most recently, Talia was attributed to YouTube star Talia Joy Castellano, a young girl battling cancer who passed away at age 13.
Talia is also an Australian Aboriginal name meaning "near water".
