Looking for Family Irby Rowell IN North South Carolina

My grandmother was Minnie Opal Rowell she married Connie S. Irby. They both came from big families she had two brothers and four sisters and he had five brothers and three sisters. So I am thinking there has to be some relatives out there some where I have ran into a dead in trying to reseach my family and would appreciate any help anyone could give. I have gotten grandparents and great grandparents that is it.
