The name ~ancestor~ suggests a fair number of your ancestors had one important asset in common: they were not afraid to put forth effort to achieve their goals. Most of them probably lived very productive lives, overcoming obstacles by the sheer strength of their will and a stubborn resolve to persevere.

On the downside, there may have been a few frustrated and angry bullies among your people who envied the apparent ease others had in finding success (while they worked hard for little reward). This may have tempted some of your less restrained predecessors to use their physical and mental strength against those who were weaker.
