I have an Elizabeth Rainbow (b. 1790 in York County, PA died 1833 in Jefferson County, KY). She was married to Robert Blair. Their son John Samuel Blair married Mary Katherine Schermmehorn. They had a daughter Julia Ann Blair (b. 1838, died 1/30/1919) who was married to Dr. John Lemaster Burdon. They lived in Webster County, Kentucky and were my grandmother's grandparents. I would like more information on the Rainbow family.
