I went with qualified no because I think we should get to choose which (if any) of our ancestors deserve our veneration.
For example, some of my ancestors were horse thieves, and the surname from that part of the family is a pseudonym that helped them evade law enforcement. No veneration there.
But some of my other ancestors did amazing things in their lives, like fighting Nazis, researching infectious diseases, and building schools in Africa. Definitely veneration-worthy.
