Calpurnia’s identity is shown as quite unknown and lost in Chapter 12 in To Kill A Mockingbird.

‘That Calpurnia led a modest double life never dawned on me.’

This shows that Calpurnia was living a double life which she didn’t feel belonged to more. By living with the Finches, she was disrespected by the white community and all she was known as, was the Finches’ maid. She was also quite separated by the black community as she spent so much time with the Finches that she did not even speak to her son, Zeebo. This suggests and she is not really accepted in both ‘societies’ and is stuck between the two.
