My great grandmother had six kids with my great grandfather. He passed away and a few years later she married his youngest brother and they had three children. What would be the proper term used to describe the different relationships here. Would you be cousins or half brothers/sisters in the different set of kids. Would your mothers new husband still be your uncle or your step dad? Would you share more DNA with your half brothers/sisters since the fathers were brothers? If so can you calculate this for me?
