Have you tried looking at spelling "Rains" and "Raynes" I have relatives who spell last name "Rains" and "Raines". I know there is a family or two in Wayne Co, KY that spells last name "Raynes". My group of Rains' is from Wayne and Clinton Co KY and Pickett and Fentress Co, TN. Ancestors migrated there from North Carolina and Virginia. Family has spread out considerably in last generation or two.
