Sleeping Beauty
Q: Hi, Is Queen Leah the official name for Aurora's mother in Sleeping Beauty? I've seen the name being used and it was used in the Disney Channel movie Descendants as well. Similarly, the names Claudia, Laura and Paula (or alternatively, Claudette, Laurette and Paulette) have been used on the internet to refer to the Bimbettes from Beauty and the Beast. I believe the Beauty and the Beast Vinylmation series also used the name 'Triplet Paula', along with 'Prince Adam' for the Prince.

A: The Queen in Sleeping Beauty was not named, probably because she had such a minor role.  None of the other names you mentioned are official, though occasionally character names are created for sequels, television series, merchandise, publications, or other uses.
