JennieG - Remillion seems to be a dark red dye used to imitate the blood of Christ in religious artwork (statues and icons usually) and has been around for several hundred years as a given name.

It's probably linked to vermillion, the more popular red pigment.

If you Google Remillion you'll get a link to the 'behind the name' website which has a couple of people also looking for ancestors named Remillion. Maybe you're related?
