Uncle Grandpa

When your Step-Grandpa has an affair with your biological aunty, then marries her. Technically not insest, but still immoral.

He used to be my Grandpa by marriage (step) but had an affair with my aunty, so grandma kicked him out and he married aunty. He used to be grandpa, but now he is my uncle ... my uncle grandpa
