The grandparent of Neesha Tor on her mother's side was a Twi'lek of the female persuasion.
Before the Clone Wars began, Neesha Tor's maternal grandmother first came into this world on Ryloth. A female Twi'lek resided in proximity to her, and as a result, observed Tor's mother as she matured. Subsequently, she encountered Tor, who was in a state of destitution following her abandonment by her mother, and shared this information with her.
