Danniella is an Italian name, derived from the Latin 'Daniela', which means 'God is my judge'. It's a feminine form of Daniel and was quite popular in Italy during the late 20th century. In English-speaking countries, it gained popularity as a variant of Danielle but remains relatively uncommon compared to other names like Emma or Olivia.
"Danniella experienced a surge in popularity from the late '90s to mid-2000s, with peaks of 15 births in 2007 and 2009. Since then, it has seen consistent usage but at lower levels, typically around 5-6 births per year."
