A source named Darth Simon at the Jedi Council forums that appears to have real connections to the Star Wars: Episode VII shoot just shared some information:
Here is some info from the winnebagos at the Puzzlewood shoot.
Darth Simon also says:
This is what could be the Daisy character name. And another kind of creature involved.
This is the general type of name I could see being used for a Star Wars character. I buy it as a possibility. I do wonder if they would actually use the real name on printed AVCO signs for characters they want to keep secret. So that could be a code name. But then again, it could just be that simple, really.
When asked if this is Daisy Ridley’s character he responded:
They say its most likely Daisy. But can’t as certain as with stuff before.
Thanks to Average Film Guy for the heads up!
