What does the name Chacha (チャチャ) mean?


I always wondered about the meaning of this name in Japanese, but couldn't
find much on Google. Can someone tell me what it means?

UPDATE: 茶々{ちゃちゃ} was a concubine to [Toyotomi
Hideyoshi](http://en.wikipedia.org/wiki/Toyotomi_Hideyoshi) in the [Sengoku
Period](http://en.wikipedia.org/wiki/Sengoku_period). I found the info [on
Wikipedia](http://en.wikipedia.org/wiki/Yodo-dono).

Additionally, I found that a fictional character form the Japanese manga
series Maken-Ki is named Akaza Chacha (藜 チャチャ). Info here:

Chacha was lady Yodo's childhood name, eldest daughter of Oichi, Oda
Nobunaga's sister. Trying to find the meaning myself.. That first kanji looks
like it's from Ocha, which is tea... But that's only the reach of my amateur
"otaku Japanese"... I can read hiragana and katakana, but I only know a few
dozen kanji, probably less than 100, which is not a lot. >_<
