Crispin Cronk's sphinxes

Crispin Cronk was a wizard who insisted on keeping several pet sphinxes in his backyard. During the 19th century, the domestication and private ownership of sphinxes was illegal and, after Cronk refused to hand his sphinxes over to the Ministry of Magic, the Ministry was forced to convict Cronk and send him to Azkaban.

It is unknown what happened to Cronk's sphinxes after this point, however, it is presumed that they were taken into care of the Beast Division of the Department for Regulation and Control of Magical Creatures.
