Tasha is a name of Slavic origin, derived from Russian "Татьяна" (Tat'yana), which means "arrival" or "appearing". It gained popularity in the West during the mid-20th century, likely due to its use by notable figures such as Tasha Tudor, an American artist and author of children's books. The name has since been adopted by various cultures, contributing to its global recognition.
"Tasha was quite popular as a baby girl name from the mid-70s to the early 80s, with peaks of 15 births in 1981 and consistently high numbers between 1977 and 1982. However, its popularity dropped off significantly by 1990."
