In page Archduchess Maria Johanna Gabriela of Austria:

"

Maria Johanna was born on 4 February 1750 at the Hofburg Palace in Vienna, Austria, as the eleventh child and eighth daughter of Francis I, Holy Roman Emperor and Empress Maria Theresa. She was raised in the Kindskammer with her many siblings, though she was particularly close with her sister Maria Josepha,[citation needed] whom was born a year after Maria Johanna in 1751. The two were educated together and had the same tutors.[1][2]
