Ivanova was a Chaser on the Bulgarian National Team at the 1994 Quidditch World Cup.

Ivanova is the feminine form of the very common Bulgarian surname Ivanov (meaning "son of Ivan"). It comes from Old Slavic Іѡаннъ (Ioannu) and Greek Ιωαννης (Ioannes) and is equivalent to the English name John. They are derived from the Hebrew name יוֹחָנָן (Yochanan) meaning "Yahweh is gracious" (Behind the Name). A famous Bulgarian of the same name was women's rights activist Dimitrana Ivanova (1881–1960) (Wikipedia).
