I know my grandpa had some eyelid shabang, but it more of the nordic fold one, my mum has the same as my grandpa but I can't find anyone with the same eyefolds as me. I don't know any of my maternal great grandparents so I don't know if it's from them but I know we got some tatar so, maybe? But I think it could be just me being underdeveloped as a baby or something.
