The name ~ancestor~ suggests you likely count a number of very crafty, smooth-talking, and polished individuals among your ~ancestor~ ancestors. Some may have taken advantage of this skill - their gift of gab stronger than their integrity. 

However, many would have used this ability to benefit themselves and others. Some would have used it to express themselves through art forms such as prose, poetry, or music. You likely count successful artists among your ancestors (and possibly a few "scam" artists). The ability to talk your way into or out of just about any situation has likely been fine-tuned over many generations, perhaps leaving traces that are part of your makeup.
