According to People magazine, the star couple's daughter takes her first name from Sunday Reed -- an early 20th-century artist's muse -- and her middle name from Urban's late grandmother, Rose.
"I have read a bit about Sunday Reed and her husband John -- she was a key mover and shaker in the arts around the beginning of the century," Kidman's father Antony explained to Australian newspaper The Daily Telegraph. "The name Sunday struck me as being a nice name for a woman, so my wife and I mentioned it."
The Telegraph adds that in January, Nicole and Keith visited a gallery by Sidney Nolan -- the artist who was inspired by muse Sunday Reed.
