Three Vintage Porcelain? & Plastic Catholic Nun Dolls with Crucifix

Description

These are special - found in a New Jersey Estate sale of a doll collector
I am selling all three together but they do appear to be made by different makers
The doll in the White clearly has a tag on the inside of her dress that states This is A Marcie Doll.  The dress has ivoried a bit.  The crucifix is metal and displays nicely.
One of the dolls in Black seems to be made in an earlier type of plastic  - not makers mark
LAST PHOTO _  Finally the other seems to be either ceramic or porcelain and might be the most unusual or eldest doll.
- she has a plastic cross - no makers marks
All the clothes will need a general cleaning or refurbishment.
Thank you for looking
