Hi Michael,
I have no futher information on the Vermillions. I was told by another Vermillion researcher who had ties with the Vermillions who lived in Warren County, Virginia that there Vermillions migrated to Virginia from Maryland and that I might also find my Thompson line there which I did only they were in Baltimore.
I did find your Ruben Vermillion and his pedegree that went back to 1659 in Maryland at the
www.familysearch.org site.
