Tanina
I was named TANINA after my Italian grandmother. Her name was Guytana, which is the feminine form of Guytano, an Italian form of Anthony. Tanina is a common nickname for Guytana in Sicily, where my grandmother was born. It is derived from the "Tan" in Guytana, plus "ina", which is a diminutive and affectionate addition, kind of like adding a "y" at the end of a name.
