I think in Africa, Adjoa is the name given to an Akan or a Baoule (a specialisation) when she is born on a Tuesday not on a Monday. Her name should be Akissi on a Monday.
The name Adwoa is pronounced as Adjua. It can be spelled in various ways, including Adwoa, Ajua, Adjoa, etc. The spelling of the name usually indicates where in Ghana the person is from and with which clan they are associated.
