Antique sleepy eye doll in box

I'm trying to dig up some information on a doll that's been in the family for some time. Unfortunately, I don't have any background information although many of the antiques in my family are German. And I can't look for a mark because she's still tied into her little box! I've spent a lot of time on fruitless research but don't know enough about dolls. Any ideas on maker / manufacturer / era?
