My mother's family name is Oriuchi. I haven't been able to find much of any information on the name. I know they came from Akita and my grandfather had something like 10 brothers and sisters, he was the youngest. His parents died when he was just a chibi kid and his sisters essentially raised him. My grandfather is still alive (in his 90s!!!) and I think he may have a living sibling or two.. Does this sound familiar to any other people with Oriuchi lineage?
