Miranda has long been one of the "lost arks" of SCA name research. While Shakespeare used it as a literary name, he did so after 1600. Literary names after 1600 aren't registerable. (Although names of real people through 1650 are usable).
Today, during a dull lunch hour, I found usable SCA documentation for Miranda:
Death Date: 10 Feb 1642
Death Place: Murcia, Murcia, Spain
The use of B- Batches from the Family Search Historical Records as documentation was approved in the January 2014 LoAR.
