Based on the available evidence, this woman's identity is not known. I can't accurately name her from the photograph alone.
What can be said with reasonable confidence is:
She appears to be an African American obstetric nurse or midwife standing outside her residence or practice.
The sign behind her :
"CLARK HOMES / OBSTETRIC NURSE / HOME NURSING"
The image is consistent with the 1930s in Mississippi, a period when Black nurses and midwives were indispensable in providing maternal and infant care to Black communities that were largely excluded from segregated hospitals.
