When using Prussian names, would they have used their names as a double barreled name, only used the middle name, or use the first?
I ask because I have many ancestors in which all females in the family are named Anna (insert middle name), Maria (insert middle name) or Johann (insert middle name). Many families have multiples with the same name but differing middle names, so I am wondering what the common naming practice was, would you say for instance:
Ex. Anna Maria Dorothea Schultz
Anna
Anna Maria
Anna Maria Dorothea
Maria
Maria Dorothea
